As a beam of light travels from one medium to another, the change in direction of the beam of light depends on:
A) the wavelength of the light
B) the index of refraction of the outgoing medium
C) the index of refraction of the incoming medium
D) the angle of incidence
E) all of the above

Question

Quizplus · Accepted Answer

The change in direction of the beam of light (refraction) depends on all the options given: 
A) the wavelength of the light - shorter wavelengths are bent more than longer wavelengths
B) the index of refraction of the outgoing medium - a higher index of refraction will bend the light more
C) the index of refraction of the incoming medium - the greater the difference in the indices of refraction, the more the light is bent
D) the angle of incidence - a greater angle of incidence results in a greater angle of refraction.
