Question

what is refraction
​

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.

Answer 2

Answer:

The shortest path need not be the quickest path. Since light is always in a hurry, it bends when it enters a different medium as it is still following the quickest path. This phenomenon of light bending in a different medium is called refraction

:)

in short when light moves from one medium to another medium it deviates from its original path and continues on another path

light bends towards normal while moving from lighter medium to denser medium

light bends away from the normal while moving from denser medium to lighter medium
