A vessel consists of two plane mirrors at right angles as shown in figure. The vessel is filled with water. The toal deviation in incident ray is

A

`0^(@)`

B

`60^(@)`

C

`90^(@)`

D

`180^(@)`

Text Solution

Verified by Experts

The correct Answer is:
D
Angle between the two plance mirrors, `theta=90^(@)`
As relection is independent of medium Deviation produced by the combination of two plane mirrors is `delta=2pi-2theta=2pi-2(pi//2)=pi=180^(@)`
