Question

What happens to the light that passes at an angle to the normal, from one material into another material in which its speed is lower?

Answer 1

Answer:

Refraction is an effect that occurs when a light wave, incident at an angle away from the normal, passes a boundary from one medium into another in which there is a change in velocity of the light. Light is refracted when it crosses the interface from air into glass in which it moves more slowly.
