Question

1. On a plane mirror, a light ray is incident at an angle of 30° to the surface of the mi
between the incident ray and the reflected ray will be (30°, 120°, 180°​

Answer 1

Answer:

Correct option is

D

120

o

Since angle of incident =angle of reflection

Hence r=30

0

And here angle of deviation,

δ=180

0

−(i+r)

δ=120

0
