Question

Refraction of light is change in the direction of propagation of light when it enters to the other medium m, is refractive index of second medium with respect to medium 1. The refracted ray deviate towards the normal or away from normal depending on the density of medium also known as optical density . Optical density should not be confused with mass density. Refraction is responsible for many interesting phenomena in atmosphere
