When light passes through two media X and Y of refraction indices 1.51 and 1.33 respectively; The speed of light in?

A. x is the same as in y
B. x and y is the same as in vacuum
C. x is higher than in y
D. y is higher than in x

Correct Answer:

Option D – y is higher than in x

Explanation

Since 1.51, the refractive index of X is greater than 1.33, the refractive index of y, the speed of light in y is higher than that in X
