What is the cause of refraction of light?

Questions

Write the basic cause of refraction of light.

Very Short Answer

Solution

When a ray of light passes from one medium to another, its direction (except for normal incidence) changes because of a change in the speed of light. Thus, refraction occurs because light travels with different speeds in different media.
