Why does a ray of light bend when it travels from one medium to another?

उत्तर
The bending of light rays when they pass obliquely from one medium to another medium is called refraction of light.
Light rays get deviated from their original path while entering from one transparent medium to another medium of different optical density. This deviation (change in direction) in the path of light is due to the change in velocity of light in the different medium. The velocity of light depends on the nature of the medium in which it travels.
