Question

Why does a ray of light actually bend while going from one medium to another?

Answer 1

Refraction of Light:

1. A ray of light bends while going from one medium to another because of the phenomena of refraction.
2. When the ray of light travels from one medium to another as the velocity of the light ray will either increase or decrease depending on the optical density of the material.
3. The other parameters on which the bending of the light ray depends are the wavelength of the light ray entering the medium and the angle at which the light ray enters.
