Dispersion occurs in a medium because
A) the index of refraction depends on wave amplitude.
B) of regular reflection.
C) of diffuse reflection.
D) the index of refraction depends on the wavelength.

Question

Quizplus · Accepted Answer

Dispersion occurs because the index of refraction of a medium varies with the wavelength of light passing through it. This causes different wavelengths (colors) of light to bend by different amounts when passing through the medium, leading to the separation of light into its component colors.
