Because the index of refraction varies slightly with wavelength,
A)white light refracts much less than black light.
B)white light refracts much more than black light.
C)the amount and direction of refraction is exactly the same for all colors of light.
D)the amount and direction of refraction is slightly different for different colors of light.

Question

Quizplus · Accepted Answer

The variation in the index of refraction with wavelength leads to the phenomenon of dispersion, where different colors of light are refracted by different amounts, resulting in a separation of colors. This means that the amount and direction of refraction is slightly different for different colors of light, and not exactly the same for all colors. Therefore, option D is the best choice.
