The angle of deviation of a light ray reflected by a plane mirror is `150^(@)`. The angle of reflection is _____.

A

`30^@`

B

`60^@`

C

`15^@`

D

`10^@`

Text Solution

Verified by Experts

The correct Answer is:
C
The angle of deviation d = 180 - 2i = 180 - 2r
150 = 180 - 2r
`2r = 30^@ = 15^@`
