Question

When refraction occurs, a change in wave speed leads to a change in wave direction?

Answer 1

Yes... that is true

Answer 2

Explanation :

Refraction is the process of bending of light when it moves from one medium to another. The bending depends on two factors :

• When the light moves from one medium to another, its speed changes. This is because the refractive indices of both mediums differ.

• Bending also depends on the angle of incidence.

When refraction occurs, a change in wave speed leads to a change in wave direction. This statement is true.

Hence, this is the required solution.
