Question

what is refraction of light?​

Answer 1

Answer:

In physics, refraction is the change in direction of a wave passing from one medium to another or from a gradual change in the medium. Refraction of light is the most commonly observed phenomenon, but other waves such as sound waves and water waves also experience refraction.

Answer 2

Refraction of Light :

The phenomenon of the bending of light rays as they travel from one medium to the other is called Refraction

( The surface separating two media is called an interface )

In other words,

The phenomenon of bending of light rays at the boundary between two media is called Refraction.
