This diagram shows white light passing through a prism and being separated into a spectrum of visible colors.  Which statement best explains how the prism changes white light into a spectrum of colors?

• The prism absorbs white light, making it possible to see the colored light.

• White light causes different molecules in the prism to radiate different colors.

• The prism changes the white light wavelength into a number of different wavelengths.

• The prism refracts each of the wavelengths that make up white light at a different angle.
