    The bending of light is called ___________________.

    Explanation
    Refraction is the phenomenon where light changes direction as it passes from one medium to another. This bending of light occurs due to the change in speed of light in different mediums. When light travels from a medium with a lower refractive index to a medium with a higher refractive index, it bends towards the normal. Conversely, when light travels from a medium with a higher refractive index to a medium with a lower refractive index, it bends away from the normal. This bending of light is what is referred to as refraction.

    1.  Sound is a vibration that travels in ________________.

    Explanation
    Sound is a form of energy that travels in waves. These waves are created by the vibration of an object, such as a speaker or a musical instrument. As the object vibrates, it causes the surrounding air particles to vibrate, creating a disturbance that travels through the air in the form of waves. These waves then reach our ears, where they are detected and interpreted by our brain as sound. Therefore, sound is a vibration that travels in waves.

    A high frequency sound has a low pitch.

    • True

    • False

    Correct Answer
    A. False
    Explanation
    A high frequency sound has a high pitch because pitch is determined by the frequency of a sound wave. The higher the frequency, the higher the pitch. Therefore, the statement that a high frequency sound has a low pitch is incorrect.

    ________________________ is the study of sound made by wildlife.

    Correct Answer
    Bioacoustics
    Explanation
    Bioacoustics is the study of sound made by wildlife. This field of study involves the analysis and interpretation of animal sounds, including their vocalizations, communication patterns, and acoustic behaviors. By studying bioacoustics, researchers can gain insights into various aspects of animal behavior, such as mating rituals, predator-prey relationships, and territorial communication. This knowledge can be valuable for understanding and conserving wildlife populations, as well as for studying the ecological impact of human activities on animal habitats.

    Nonvisible light made of low frequency wavelengths is called ___________________ light.

    Correct Answer
    infrared
    Explanation
    Infrared light refers to nonvisible light that consists of low frequency wavelengths. It is a form of electromagnetic radiation that lies between the visible light and microwave regions of the electromagnetic spectrum. Infrared light is commonly associated with heat and is used in various applications such as night vision technology, remote controls, and thermal imaging.

    An Army jet flies faster than Mach I.  Its speed is _______________.

    Correct Answer
    supersonic
    Explanation
    An Army jet flying faster than Mach I is considered supersonic. The term "supersonic" refers to speeds that exceed the speed of sound, which is approximately 767 miles per hour or 1,235 kilometers per hour at sea level. Therefore, the correct answer is "supersonic."

     Sound too low for our ears to detect is called _______________________.  

    Correct Answer
    infrasound
    Explanation
    Infrasound refers to sound waves that have a frequency lower than what the human ear can detect. These sound waves typically have a frequency below 20 Hz. While humans may not be able to hear infrasound, some animals, such as elephants and whales, are capable of detecting and communicating using these low-frequency waves. Infrasound can also be produced by natural events like earthquakes and volcanic eruptions, as well as man-made sources such as machinery and explosions.

    Ships and submarines use a system called ____________________ that was developed by studying echolocation in bats and dolphins.

    Correct Answer
    sonar
    Explanation
    Ships and submarines use a system called sonar that was developed by studying echolocation in bats and dolphins. Sonar is a technology that uses sound waves to detect objects underwater. Bats and dolphins use echolocation, a natural ability to navigate and locate objects by emitting sound waves and listening to the echoes. Scientists studied this ability and applied it to the development of sonar systems, allowing ships and submarines to navigate and detect underwater objects using sound waves.

    What "color" is produced when you mix cyan, magenta, and yellow?

    Correct Answer
    black
    Explanation
    When cyan, magenta, and yellow are mixed together, they absorb all colors of light except for black. This means that they reflect very little light and appear as black to our eyes. This is why mixing these three primary colors results in the production of black.

    Sunburn is caused by _________________ light.

    Correct Answer
    ultraviolet
    Explanation
    Sunburn is caused by ultraviolet light. Ultraviolet (UV) light is a type of electromagnetic radiation that comes from the sun and is invisible to the naked eye. When the skin is exposed to excessive amounts of UV radiation, it can cause damage to the DNA in skin cells, leading to inflammation and redness known as sunburn. UV light is divided into three types: UVA, UVB, and UVC. UVB is primarily responsible for sunburn, as it has a shorter wavelength and higher energy that can penetrate the outer layers of the skin.

    Light is composed of wavelengths made of _____________________.

    • Electrons

    • Photons

    • Vibrations

    • Colors

    Correct Answer
    A. Photons
    Explanation
    Light is composed of wavelengths made of photons. Photons are elementary particles that carry energy and have zero mass. They behave both as particles and as waves, and they are the fundamental units of light. When light is emitted or absorbed, it does so in discrete packets of energy called photons. These photons have different wavelengths, which determine the color of light. Therefore, photons are the correct answer to this question.
