The refractive indices between glass and oil are quite similar, as compared to the refractive indices between glass and air, which are quite different. Therefore, in which of the following situations will light bend the most?
A) When passing between glass and air
B) When passing between glass and oil

Question

Quizplus · Accepted Answer

Light bends more when there is a greater difference in refractive indices between two media. Since the refractive indices between glass and air are quite different, light will bend more when passing between glass and air compared to glass and oil.
