Questions and Answers
  • 1. 

    Color depends on what characteristic of light?

    • A.

      Its frequency

    • B.

      Its amplitude

    • C.

      Both of these

    Correct Answer
    A. Its frequency
    Explanation
    The color of light depends on its frequency. Frequency refers to the number of complete cycles of a wave that occur in a second. Different frequencies of light correspond to different colors in the visible spectrum. For example, light with a high frequency appears blue or violet, while light with a low frequency appears red. Therefore, the frequency of light determines the color we perceive.

    Rate this question:

  • 2. 

    When the frequency of light matches the natural frequency of molecules in a material, light is

    • A.

      Absorbed.

    • B.

      Transmitted.

    • C.

      Reflected.

    • D.

      None of these

    Correct Answer
    A. Absorbed.
    Explanation
    When the frequency of light matches the natural frequency of molecules in a material, light is absorbed. This is because the energy of the light waves is transferred to the molecules, causing them to vibrate or move to a higher energy state. This absorption of light can lead to various effects, such as heating of the material or triggering chemical reactions.

    Rate this question:

  • 3. 

    The color of an opaque object is the same as the light that is

    • A.

      Transmitted.

    • B.

      Absorbed.

    • C.

      Reflected.

    • D.

      All of these

    • E.

      None of these

    Correct Answer
    C. Reflected.
    Explanation
    When light hits an opaque object, it is not transmitted through it, nor is it absorbed completely. Instead, the object reflects certain wavelengths of light, which are then detected by our eyes as color. Therefore, the correct answer is "reflected."

    Rate this question:

  • 4. 

    What color light is transmitted by a piece of blue glass?

    • A.

      Red

    • B.

      White

    • C.

      Blue

    • D.

      Yellow

    • E.

      Orange

    Correct Answer
    C. Blue
    Explanation
    Blue glass transmits blue light because it selectively absorbs all other colors of light and only allows blue light to pass through. This is due to the molecular structure of the glass, which absorbs certain wavelengths of light and reflects or transmits others. Therefore, when light passes through a piece of blue glass, only the blue wavelengths are able to pass through, resulting in the transmitted light appearing blue.

    Rate this question:

  • 5. 

    The brightest color emitted by the sun is

    • A.

      Red.

    • B.

      Orange.

    • C.

      Yellow-green.

    • D.

      Green-blue.

    • E.

      Violet.

    Correct Answer
    C. Yellow-green.
    Explanation
    The sun emits light across a wide range of colors, but the brightest color it emits is yellow-green. This is because the sun's surface temperature is around 5,500 degrees Celsius, which corresponds to the peak of its blackbody radiation curve in the yellow-green part of the spectrum. This color is most dominant and visible to our eyes, making it the brightest color emitted by the sun.

    Rate this question:

  • 6. 

    The solar radiation curve is

    • A.

      A dent in the otherwise spherical sun.

    • B.

      The path taken by the sun as it travels around the Earth.

    • C.

      A plot of brightness of sunlight versus its frequency.

    • D.

      A plot of the colors of sunlight versus their frequencies.

    • E.

      A plot of light intensity versus distance from the sun.

    Correct Answer
    C. A plot of brightness of sunlight versus its frequency.
    Explanation
    The solar radiation curve refers to a plot of the brightness of sunlight versus its frequency. This means that it shows how the brightness of sunlight changes as the frequency of the light waves varies. It does not represent the path taken by the sun or the colors of sunlight. It also does not show the relationship between light intensity and distance from the sun.

    Rate this question:

  • 7. 

    Which will warm up quicker in sunlight?

    • A.

      A piece of colored glass

    • B.

      A piece of clear glass

    • C.

      Both the same

    Correct Answer
    A. A piece of colored glass
    Explanation
    A piece of colored glass will warm up quicker in sunlight because colored objects absorb more light and heat compared to clear objects. The color of the glass determines which wavelengths of light it absorbs and reflects. Clear glass allows most of the light to pass through, while colored glass absorbs certain wavelengths, converting them into heat energy. Therefore, the colored glass will absorb more sunlight and warm up faster than the clear glass.

    Rate this question:

  • 8. 

    Light shines on a pane of green glass and a pane of clear glass. The temperature will be higher in the

    • A.

      Clear glass.

    • B.

      Green glass.

    • C.

      Neither – it will be the same in each.

    Correct Answer
    B. Green glass.
    Explanation
    When light shines on a pane of green glass, the glass absorbs most of the light except for the green wavelength, which is reflected back. This absorption of light by the green glass causes it to heat up more compared to the clear glass, which allows more light to pass through without being absorbed. Therefore, the temperature will be higher in the green glass.

  • 9. 

    The colored dots that make up the color on a TV screen are

    • A.

      Red, blue, yellow.

    • B.

      Red, blue, green.

    • C.

      Yellow, blue, green.

    • D.

      Magenta, cyan, yellow.

    • E.

      Red, green, yellow.

    Correct Answer
    B. Red, blue, green.
    Explanation
    The correct answer is red, blue, green. This is because red, blue, and green are the primary colors of light used in additive color mixing. By combining different amounts of these three colors, all other colors can be created on a TV screen.

    Rate this question:

  • 10. 

    If three primary colors of light are to shine on a white wall to produce a white spot, the primaries must be

    • A.

      Additive.

    • B.

      Subtractive.

    • C.

      Multiplicative.

    • D.

      Divisive.

    Correct Answer
    A. Additive.
    Explanation
    When three primary colors of light are combined additively, they create white light. This is because additive color mixing involves combining different wavelengths of light to produce a wider range of colors. In this case, the three primary colors of light would need to be combined in order to create a white spot on the white wall. Therefore, the correct answer is additive.

    Rate this question:

  • 11. 

    Complementary colors are two colors that

    • A.

      Look good together.

    • B.

      Are additive primary colors.

    • C.

      Are subtractive primary colors.

    • D.

      Produce white light when added together.

    • E.

      Are right for each other.

    Correct Answer
    D. Produce white light when added together.
    Explanation
    Complementary colors are pairs of colors that, when combined, produce white light. This is because complementary colors are located opposite each other on the color wheel, and when they are mixed, they cancel out each other's wavelengths, resulting in white light. This phenomenon is known as color subtraction, where the colors subtract from each other to create white. Therefore, the correct answer is that complementary colors produce white light when added together.

    Rate this question:

  • 12. 

    The complementary color of blue is

    • A.

      Red.

    • B.

      Green.

    • C.

      Yellow.

    • D.

      Cyan.

    • E.

      Magenta.

    Correct Answer
    C. Yellow.
    Explanation
    The complementary color of blue is yellow because complementary colors are pairs of colors that, when combined, create a neutral color (such as white or gray). Blue and yellow are complementary colors because they are located opposite each other on the color wheel. When blue and yellow are mixed together, they create a neutral gray color.

    Rate this question:

  • 13. 

    Magenta light is really a mixture of

    • A.

      Red and blue light.

    • B.

      Red and cyan light.

    • C.

      Red and yellow light.

    • D.

      Yellow and green light.

    • E.

      None of these

    Correct Answer
    A. Red and blue light.
    Explanation
    Magenta light is perceived as a single color, but it is actually a mixture of red and blue light. When red and blue light are combined, they create the sensation of magenta. This is because magenta is not a spectral color and cannot be created by a single wavelength of light. Instead, it is created by stimulating both the red and blue cones in our eyes, which results in the perception of magenta. Therefore, the correct answer is red and blue light.

    Rate this question:

  • 14. 

    Colors seen on TV results from color

    • A.

      Addition.

    • B.

      Subtraction.

    • C.

      Either of these

    • D.

      Neither of these

    Correct Answer
    A. Addition.
    Explanation
    The colors seen on TV result from color addition. This means that different colors are combined to create the desired hues. In TV screens, three primary colors (red, green, and blue) are used to produce a wide range of colors by varying their intensities. By adding these colors together in different proportions, the TV is able to display a full spectrum of colors. This process is known as additive color mixing and is the reason behind the vibrant and diverse colors we see on TV screens.

    Rate this question:

  • 15. 

    Colors seen on the cover of our physics book result from color

    • A.

      Addition.

    • B.

      Subtraction.

    • C.

      Either of these

    • D.

      Neither of these

    Correct Answer
    B. Subtraction.
    Explanation
    The colors seen on the cover of our physics book result from color subtraction. This means that the colors we perceive are the result of certain wavelengths of light being absorbed or subtracted by the pigments on the cover, while the remaining wavelengths are reflected and reach our eyes, creating the perception of color. This is different from color addition, where colors are produced by combining different wavelengths of light.

    Rate this question:

  • 16. 

    How many colors of ink are used to print full-color pictures?

    • A.

      One plus black

    • B.

      Two plus black

    • C.

      Three plus black

    • D.

      Four plus black

    • E.

      Six plus black

    Correct Answer
    C. Three plus black
    Explanation
    Full-color pictures are typically printed using a combination of cyan, magenta, yellow, and black inks. These four colors, also known as CMYK, are used to create a wide range of colors and shades. In addition to these three primary colors, black ink is added to enhance contrast and depth in the image. Therefore, the correct answer is "three plus black," indicating that three colors (cyan, magenta, and yellow) are used along with black ink to print full-color pictures.

    Rate this question:

  • 17. 

    Different colors of light correspond to different light

    • A.

      Velocities.

    • B.

      Intensities.

    • C.

      Polarities.

    • D.

      Frequencies.

    • E.

      None of these

    Correct Answer
    D. Frequencies.
    Explanation
    Different colors of light correspond to different frequencies. This is because color is determined by the wavelength of light, and frequency and wavelength are inversely proportional. Therefore, light with a shorter wavelength (such as blue or violet) has a higher frequency, while light with a longer wavelength (such as red or orange) has a lower frequency. This is why we see different colors in a rainbow or when light passes through a prism.

    Rate this question:

  • 18. 

    A mixture of red and green pigments appears

    • A.

      Orange.

    • B.

      Yellow.

    • C.

      Magenta.

    • D.

      Blue.

    • E.

      Blackish brown.

    Correct Answer
    E. Blackish brown.
    Explanation
    When red and green pigments are mixed together, they create a color that is a combination of the two. In this case, the mixture of red and green pigments would result in a color that is a dark brown, almost blackish in appearance. This is because red and green are complementary colors, meaning they are opposite each other on the color wheel. When complementary colors are mixed together, they tend to neutralize each other and create a darker, more muted color.

    Rate this question:

  • 19. 

    A mixture of cyan and yellow pigments appears

    • A.

      Orange.

    • B.

      Green.

    • C.

      Magenta.

    • D.

      Blue.

    • E.

      Blackish brown.

    Correct Answer
    B. Green.
    Explanation
    When cyan and yellow pigments are mixed together, they absorb certain wavelengths of light and reflect others. Cyan pigment absorbs red light, while yellow pigment absorbs blue light. As a result, when these two pigments are mixed, they absorb both red and blue light, leaving green light to be reflected. Therefore, the mixture of cyan and yellow pigments appears green.

    Which interacts more with sounds of relatively high frequencies?

    • A.

      Large bells

    • B.

      Small bells

    • C.

      Both the same

    Correct Answer
    B. Small bells
    Explanation
    Small bells interact more with sounds of relatively high frequencies because they have smaller dimensions and a higher resonant frequency. The smaller size of the bell allows it to vibrate at a higher frequency when struck, producing higher-pitched sounds. In contrast, large bells have larger dimensions and a lower resonant frequency, causing them to interact more with sounds of lower frequencies.

    Rate this question:

  • 22. 

    Which interacts more with light of relatively high frequencies?

    • A.

      Large particles

    • B.

      Small particles

    • C.

      Both the same

    Correct Answer
    B. Small particles
    Explanation
    Small particles interact more with light of relatively high frequencies because of a phenomenon called Rayleigh scattering. When light interacts with small particles, such as molecules or tiny particles, the wavelength of the light becomes comparable to the size of the particles. This causes the light to scatter in all directions, with shorter wavelengths (higher frequencies) being scattered more efficiently. As a result, small particles tend to scatter light of higher frequencies more effectively than large particles.

    Rate this question:

  • 23. 

    The sky is blue because air molecules in the sky act as tiny

    • A.

      Mirrors which reflect only blue light.

    • B.

      Resonators which scatter blue light.

    • C.

      Sources of white light.

    • D.

      Prisms.

    • E.

      None of these

    Correct Answer
    B. Resonators which scatter blue light.
    Explanation
    Air molecules in the sky act as tiny resonators which scatter blue light. When sunlight passes through the Earth's atmosphere, it interacts with the air molecules. The shorter blue wavelengths of light are scattered more than the longer wavelengths, such as red and yellow. This scattering process is known as Rayleigh scattering, and it is responsible for the blue color of the sky. The air molecules act as resonators, absorbing and re-emitting the blue light in all directions, resulting in the blue appearance of the sky.

    Rate this question:

  • 24. 

    A whitish sky is evidence that the atmosphere contains

    • A.

      Predominantly small particles.

    • B.

      Predominantly large particles.

    • C.

      A mixture of particle sizes.

    • D.

      Water vapor.

    • E.

      Pollutants.

    Correct Answer
    C. A mixture of particle sizes.
    Explanation
    A whitish sky is evidence that the atmosphere contains a mixture of particle sizes. This is because when the atmosphere contains particles of different sizes, they scatter sunlight in different ways. The scattering of sunlight by small particles causes the sky to appear blue, while the scattering by larger particles can cause the sky to appear white or gray. Therefore, a whitish sky suggests the presence of both small and large particles in the atmosphere.

    Rate this question:

  • 25. 

    Sunsets are red, blue jays are blue; the reason's the same:

    • A.

      Scattered sunlight – nothing new.

    • B.

      Pigments that reflect in the blue.

    • C.

      Aerosols and all such goo.

    • D.

      No one knows, but it is true.

    Correct Answer
    A. Scattered sunlight – nothing new.
    Explanation
    The given answer, "scattered sunlight - nothing new," is the correct explanation for the phenomenon described in the passage. Sunsets appear red because the light from the sun is scattered by particles in the atmosphere, causing shorter blue and green wavelengths to scatter more and longer red wavelengths to dominate. Similarly, blue jays appear blue because their feathers contain pigments that reflect blue light. In both cases, the color is a result of light scattering, which is a well-known phenomenon. The mention of aerosols and goo suggests that there may be additional factors contributing to the scattering, but the main reason is still scattered sunlight.

    Rate this question:

  • 26. 

    The sky is the deepest blue

    • A.

      Just before a rainstorm.

    • B.

      During a rainstorm.

    • C.

      Just after a rainstorm.

    • D.

      When the air is humid.

    • E.

      Just before sunset.

    Correct Answer
    C. Just after a rainstorm.
    Explanation
    The correct answer is just after a rainstorm. This is because after a rainstorm, the sky tends to clear up and the clouds disperse, allowing more sunlight to pass through. As a result, the sky appears deep blue. During a rainstorm, the sky is usually covered with dark clouds, and just before a rainstorm, the sky may appear gray or overcast. When the air is humid, the sky may appear hazy or have a lighter shade of blue. Just before sunset, the sky often takes on warm colors such as orange or pink, but not necessarily the deepest blue.

    Rate this question:

  • 27. 

    Red sunsets are due to lower frequencies of light that

    • A.

      Are scattered from larger particles in the air.

    • B.

      Are refracted from larger particles in the air.

    • C.

      Are reflected by clouds and relatively large particles in the air.

    • D.

      Survive being scattered in the air.

    • E.

      Appear reddish orange to the eye.

    Correct Answer
    D. Survive being scattered in the air.
    Explanation
    Red sunsets occur because the lower frequencies of light, such as red and orange, are able to survive being scattered in the air. When the sun is low on the horizon, its light has to pass through a larger portion of the Earth's atmosphere, which scatters the shorter wavelengths of light, such as blue and green. However, the longer wavelengths, like red and orange, are able to pass through the atmosphere without being scattered as much, resulting in a red sunset.

    Rate this question:

  • 28. 

    The sun is more likely to appear red at sunset than in the middle of the day as a result of the

    • A.

      Scattering of lower frequencies by larger particles in the air.

    • B.

      Longer path of air through which sunlight travels.

    • C.

      Lower frequencies of light emitted late in the day by the sun.

    • D.

      Pollutants emitted by humans in daylight hours.

    • E.

      Absorption effects of the smaller particles in the air.

    Correct Answer
    B. Longer path of air through which sunlight travels.
    Explanation
    The sun is more likely to appear red at sunset than in the middle of the day because the longer path of air through which sunlight travels at sunset causes the shorter wavelengths of light (blue and green) to scatter more, leaving behind the longer wavelengths (red and orange) which are more visible to our eyes.

    Rate this question:

  • 29. 

    A variety of sunset colors is evidence for a variety of

    • A.

      Elements in the sun.

    • B.

      Apparent atmospheric thicknesses.

    • C.

      Atmospheric particles.

    • D.

      Atmospheric temperatures.

    • E.

      Primary colors.

    Correct Answer
    C. Atmospheric particles.
    Explanation
    The variety of sunset colors is evidence for a variety of atmospheric particles. When sunlight passes through the Earth's atmosphere during sunset, it scatters off the particles present in the atmosphere. The scattering process causes the different colors of light to separate, resulting in the variety of colors observed during a sunset. Therefore, the presence of different atmospheric particles leads to the variety of sunset colors.

    The whiteness of clouds is evidence in the clouds for a variety of

    • A.

      Particle sizes.

    • B.

      Molecules.

    • C.

      "seeds" upon which condensation of cloud material forms.

    • D.

      Light intensities.

    • E.

      Water prisms.

    Correct Answer
    A. Particle sizes.
    Explanation
    The whiteness of clouds is evidence for a variety of particle sizes. Clouds appear white because they contain a large number of tiny water droplets or ice crystals. These particles scatter sunlight in all directions, causing the cloud to appear white. The size of the particles in the cloud determines how they scatter light, with smaller particles scattering shorter wavelengths (blue light) more effectively, giving the cloud a white appearance. Therefore, the presence of different particle sizes in the cloud contributes to its whiteness.

    The greenish blue of water is evidence for the

    • A.

      Reflection of greenish-blue light.

    • B.

      Reflection of red light.

    • C.

      Absorption of greenish-blue light.

    • D.

      Absorption of red light.

    • E.

      Interaction between green and blue frequencies of light.

    Correct Answer
    D. Absorption of red light.
    Explanation
    The greenish blue color of water is evidence for the absorption of red light. When white light, which is made up of all the colors of the visible spectrum, passes through water, the water molecules selectively absorb certain colors of light. In this case, the water molecules absorb the red light, while allowing the greenish-blue light to be transmitted or reflected, resulting in the observed color of water.

    Rate this question:

  • 32. 

    The part of the electromagnetic spectrum most absorbed by water is

    • A.

      Infrared.

    • B.

      Lower frequencies in the visible.

    • C.

      Middle frequencies in the visible.

    • D.

      Higher frequencies in the visible.

    • E.

      Ultraviolet.

    Correct Answer
    A. Infrared.
    Explanation
    Water molecules have a specific vibrational frequency that corresponds to the infrared region of the electromagnetic spectrum. When infrared radiation interacts with water, it causes the water molecules to vibrate and absorb the energy. This absorption of infrared radiation by water is what makes it the part of the electromagnetic spectrum most absorbed by water.

    • E.

      No color – black.

    Correct Answer
    E. No color – black.
    Explanation
    In deep water where sunlight is dim, there is not enough light for colors to be perceived. Therefore, the red crab would appear black because it is not reflecting any light and absorbing all the colors.

    A sheet of red paper will look black when illuminated with

    • A.

      Red light.

      Yellow light.

    • C.

      Magenta light.

    • D.

      Cyan light.

    • E.

      None of these

    Correct Answer
    C. Magenta light.
    Explanation
    When a sheet of red paper is illuminated with magenta light, the paper will appear black. This is because magenta light contains both red and blue wavelengths, but no green wavelength. Since red paper reflects red light and absorbs blue and green light, when illuminated with magenta light, the red light is absorbed and only the blue light is reflected. As a result, the paper appears black.

      Blue light.

    • B.

      Cyan light.

    • C.

      Yellow light.

    • D.

      Magenta light.

    • E.

      None of these

    Correct Answer
    C. Yellow light.
    Explanation
    When a blue object is illuminated with yellow light, the blue object will appear black. This is because yellow light is the complementary color of blue. When these two colors are combined, they cancel each other out, resulting in the perception of black.

    If sunlight were green instead of white, the most comfortable color to wear on a hot day would be

    • A.

      Magenta.

    • B.

      Yellow.

    • C.

      Green.

    • D.

      Blue.

    • E.

      Violet.

    Correct Answer
    C. Green.
    Explanation
    If sunlight were green instead of white, the most comfortable color to wear on a hot day would be green. This is because green is the complementary color to red, which is the color that is absorbed the most by our skin. Since green would be the dominant color in the sunlight, wearing green would help to reflect and deflect the green light, reducing the amount of heat absorbed by the body and making it more comfortable on a hot day.

    If sunlight were green instead of white, the most comfortable color to wear on a cold day would be

    • A.

      Magenta.

    • B.

      Yellow.

    • C.

      Green.

    • D.

      Blue.

    • E.

      Violet.

    Correct Answer
    A. Magenta.
    Explanation
    If sunlight were green instead of white, the most comfortable color to wear on a cold day would be magenta. This is because magenta is a warm color that contains red and blue, which can help to absorb and retain heat. Wearing magenta would help to keep the body warm in the absence of the usual warmth provided by white sunlight.

    Distant dark colored hills appear blue because that is the color of the

    • A.

      Atmosphere between the observer and the hills.

    • B.

      Selectively reflected light that reaches a distant observer.

    • C.

      Reflected light that survives scattering.

    • D.

      Sky that is reflected off the hills.

    Correct Answer
    A. Atmosphere between the observer and the hills.
    Explanation
    Distant dark colored hills appear blue because that is the color of the atmosphere between the observer and the hills. When light from the hills reaches the observer, it has to pass through the atmosphere. The atmosphere scatters shorter wavelengths of light (blue) more than longer wavelengths (red). As a result, more blue light is scattered towards the observer, making the hills appear blue.

    Distant snow covered hills appear yellowish because that is the color of the

    • A.

      Atmosphere between the observer and the hills.

    • B.

      Selectively reflected light that reaches a distant observer.

    • C.

      Reflected light that survives scattering.

    • D.

      Sky that is reflected off the hills.

    Correct Answer
    C. Reflected light that survives scattering.
    Explanation
    When light passes through the atmosphere, it gets scattered by the molecules and particles present in the air. This scattering causes the blue light to be scattered more than the other colors of light, making the sky appear blue. However, some of the light that is scattered by the atmosphere and reaches the distant observer is not scattered as much and retains its original color. In the case of distant snow-covered hills, the scattered blue light is mostly absorbed or scattered away, leaving behind the other colors of light, particularly the longer wavelength colors like yellow. Therefore, the hills appear yellowish to the observer because it is the reflected light that survives scattering.

    If molecules in the sky scattered orange light instead of blue light, sunsets would be colored

    • A.

      Orange.

    • B.

      Yellow.

    • C.

      Green.

    • D.

      Blue.

    • E.

      None of these

    Correct Answer
    D. Blue.
    Explanation
    If molecules in the sky scattered orange light instead of blue light, sunsets would be colored blue. This is because during sunset, the sunlight has to pass through a larger portion of the Earth's atmosphere, causing more scattering of shorter wavelength light. If the molecules in the sky scattered orange light, which has a longer wavelength than blue light, then the blue light would be filtered out and the remaining light would appear orange. Therefore, the correct answer is blue.

    If the atmosphere were about 40 times thicker, at noon the sun would appear

    • A.

      Red-orange.

    • B.

    • E.

      None of these

    Correct Answer
    A. Red-orange.
    Explanation
    If the atmosphere were about 40 times thicker, the increased density of air molecules would scatter more of the shorter wavelength blue and green light. This would make the sunlight that reaches our eyes appear more red and orange in color. Therefore, at noon the sun would appear red-orange.

    The atmosphere of Jupiter is more than 1000 km thick. From the planet's surface, the noon-day sun would appear

    • A.

      White.

    • B.

      Faintly white.

    • C.

      Not at all.

    • D.

      None of these

    Correct Answer
    D. None of these
    Explanation
    The atmosphere of Jupiter is composed mainly of hydrogen and helium, which scatter sunlight in different ways compared to Earth's atmosphere. Therefore, the noon-day sun would not appear white, faintly white, or not at all as it does on Earth. Instead, it would appear as different colors due to the scattering of sunlight by Jupiter's atmospheric gases.

    • C.

      Yellowish.

    • D.

      Reddish.

    • E.

      Untinted.

    Correct Answer
    D. Reddish.
    Explanation
    On a planet where atmospheric gases are red, the distant dark colored hills would appear reddish. This is because the atmosphere of the planet would cause the light to be scattered and absorbed in such a way that the hills would be perceived as having a reddish hue. The color of the atmosphere affects the way we perceive the colors of objects in the distance, and in this case, the red atmospheric gases would make the hills appear reddish.

    • E.

      Untinted.

    Correct Answer
    A. Bluish.
    Explanation
    On a planet where atmospheric gases are yellow, distant snow-covered hills would look bluish. This is because when sunlight passes through the yellow atmosphere, the blue light is scattered more than other colors due to its shorter wavelength. As a result, the scattered blue light reaches our eyes, making the distant snow-covered hills appear bluish.

      Refraction of sunsets and sunrises all around the world.

    • B.

      Infrared light continually emitted by the moon.

      Faintly radiating atoms in our own atmosphere when sunlight is not incident upon them.

    • E.

      Dim light that is incident upon the moon by Jupiter and other planets.

    Correct Answer
    A. Refraction of sunsets and sunrises all around the world.
    Explanation
    The redness of the lunar eclipse is evidence for the refraction of sunsets and sunrises all around the world. During a lunar eclipse, the Earth blocks direct sunlight from reaching the moon. However, some sunlight still manages to reach the moon by bending or refracting around the Earth's atmosphere. This refracted sunlight passes through the Earth's atmosphere, which scatters shorter wavelengths of light and allows longer wavelengths (such as red) to reach the moon. As a result, the moon appears red during a lunar eclipse, providing evidence for the refraction of sunsets and sunrises worldwide.
