If angle fo incidence of a light ray on ...

If angle fo incidence of a light ray on a plane mirror is `30^(@)` , then

A

The angle of reflection is `30^(@)`

B

The glancing angle of incidence is `60^(@)`

C

The angle of deviation is `120^(@)`

D

All of these

Text Solution

Verified by Experts

The correct Answer is:
D
Angle of incidence is equal to angle of reflection according to laws of reflection. Glancing angle of incidence is equal to the difference between `90^(@)` and angle of incidence. Angle of incidence of deviation is twice the glancing angle of incidence.
