Dispersion Of Light - Quiz

Quiz Preview

  • 2. 

    How are the colors of the rainbow formed?

    • From the sun hitting water.

    • From light hitting objects.

    • Through different wavelengths of refracted light.

    Correct Answer
    A. Through different wavelengths of refracted light.
    Explanation
    The colors of the rainbow are formed through different wavelengths of refracted light. When sunlight passes through water droplets in the atmosphere, it undergoes refraction and dispersion. This causes the different colors of light to separate and form a circular arc in the sky, known as a rainbow. Each color of the rainbow corresponds to a specific wavelength, with red having the longest wavelength and violet having the shortest.

    What causes light to refract off of certain objects?

    • When the beam of light goes through the object, the light bounces off, because the light is pointed at an angle.

    • The object is not transparent.

    • The object is transparent.

    Correct Answer
    A. When the beam of light goes through the object, the light bounces off, because the light is pointed at an angle.
    Explanation
    When light passes through an object, it can change direction due to the change in speed caused by the different density of the material. This change in direction is called refraction. The angle at which the light is pointed as it enters the object determines the angle at which it will bounce off. Therefore, when the beam of light goes through the object, it bounces off at an angle, causing the light to refract off of certain objects.

    Rainbows are just straight lines across the sky.

    • No, they are full circles.

    • They are a half cresent.

    Correct Answer
    A. No, they are full circles.
    Explanation
    Rainbows are not just straight lines across the sky, but they are actually full circles. Although we usually only see a semicircle due to the ground obstructing the bottom half, rainbows are actually complete circles. This can be observed from high altitudes or in certain atmospheric conditions such as from an airplane or on top of a mountain. The full circle of a rainbow is formed when sunlight is reflected and refracted inside raindrops, creating a circular pattern of colors in the sky.

    Rate this question:

  • 5. 

    Which colors of the rainbow have the longest wavelengths? (There is more than one answer!)

    • Violet

    • Orange

    • Yellow

    • Indigo

    • Red

    Correct Answer(s)
    A. Orange
    A. Yellow
    A. Red
    Explanation
    Orange, yellow, and red are the colors of the rainbow that have the longest wavelengths. Wavelength is a measure of the distance between two corresponding points on a wave, such as the peak to peak or trough to trough. The longer the wavelength, the lower the frequency of the wave. In the visible spectrum, red light has the longest wavelength, followed by orange and then yellow. These colors appear towards the end of the rainbow and are associated with lower energy and longer wavelengths compared to colors like violet and indigo, which have shorter wavelengths.
