A ray of light, which is traveling in air, is incident on a glass plate at a 45° angle. The angle of refraction in the glass
A)is less than 45°.
B)is greater than 45°.
C)is equal to 45°.
D)could be any of the above; it all depends on the index of refraction of glass.

Question

Quizplus · Accepted Answer
