• Various shades of gray

• Only three colors of light

• Seven colors of the rainbow

• Thousands of different colors

What happens to white light when it passes through a prism?

• It is absorbed by the prism and no light comes out.

• It is reflected back as white light.

• The shorter wavelengths are bent more than the longer wavelengths, separating the colors.

• The light is intensified and exits as a single bright beam.

How are the colors of a rainbow produced?

• By the reflection of sunlight off the surface of the moon.

• Water droplets separate the colors of sunlight, producing a rainbow.

• By the dispersion of moonlight through crystals in the atmosphere.

• Sunlight is absorbed by the atmosphere, leaving only the colors of the rainbow.

What determines the color of an object as perceived by the human eye?

• The color of the object itself

• The color of light that the object absorbs

• The color of light that reaches the eye from the object
