Question

Q.23 Explain the phenomenon of refraction of light.Also define angle of incidence and angle of refraction of light
​

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.

ANGLE OF INCIDENCE

the angle that a line (such as a ray of light) falling on a surface or interface makes with the normal drawn at the point of incidence.

ANGLE OF REFRACTION

the angle that the refracted ray makes with the normal line is referred to as the angle of refraction. The angle of incidence and angle of refraction are denoted by the following symbols: = angle of incidence.
