Refraction is the change in direction of a wave, caused by the change in the wave's speed. ... For example, when a light wave travels through air and then passes into water, the wave will slow and change direction. As light goes into a medium which is denser, the light ray will 'bend' toward the normal.

Answer 2

Answer:

Refraction is nothing but it is just the change in direction of a wave passing from one medium to another medium or from a gradual change in medium.
