When light passing through a prism undergoes dispersion, the effect is a due to:
A) different wavelengths traveling at different speeds.
B) different wavelengths refracting differently.
C) different wavelengths having different indices of refraction.
D) all of the above.

Question

Quizplus · Accepted Answer

Dispersion occurs because different wavelengths of light have different indices of refraction, causing them to refract at different angles and travel at different speeds through the prism.
