Question

OR
Why does a ray of light bend when it travels from one medium into
another?​

Answer 1

Answer:

A ray of light bends while going from one medium to another because of the phenomena of refraction. 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.

Answer 2

Answer:

A ray of light bands well going from one medium to another because of the phenomenon of refraction. When the Ray of light travels from one medium to another as the velocity of the light ray will either increase or decrease dependent on the optical density of the material.
