Question

What is Refraction.............

Answer 1

What is Refraction?

Good question,

Here is your perfect answer!

The bending of a light when it goes from one medium to another is called as refraction.

It is due to the difference in speed of light in two different mediums.

When light goes from a rarer to denser, it moves towards the normal,

While when light goes from a denser to rarer medium, it goes away from the normal.

Answer 2

Answer:

Refraction means when the light waves are bent, or change its direction when they enter a new medium.

This will happens because as the wave enters the new medium it changes its speed.

It moves in a material of one density with the other density material.
