Two mirrors are inclined at angle theta...

Two mirrors are inclined at angle `theta` as shown in figure. Light rays are incident parallel to one of mirrors. Light will start retracing its path after the reflection if

A

`theta = 45^(@)`

B

`theta = 30^(@)`

C

`theta = 60^(@)`

D

all three

Text Solution

Verified by Experts

The correct Answer is:
B

`DeltaOAB implies theta + theta + 90 + theta = 180^(@), implies theta= 30^(@)`
