Q. In refraction, light waves are bent on passing from one medium to the second medium, because, in the second medium
A) The frequency is different
B) The coefficient of elasticity is different
C) The speed is different
D) The amplitude is smaller
Explanation
(c) Refractive index of refracted medium w.r.t. incident medium
$= \frac{Speed\ in\ incident\ medium}{Speed\ in\ refracted\ medium}$
