The separation of white light into colors by a prism is associated with:
A)total internal reflection
B)partial reflection from each surface
C)variation of index of refraction with wavelength
D)a decrease in the speed of light in the glass
E)selective absorption of various colors

Question

Quizplus · Accepted Answer

The variation of index of refraction with wavelength causes each color of light to bend at a different angle as it passes through the prism, resulting in the separation of white light into its component colors.
