What is the angle which the rays of the sun must make with the surface of water (n=1.33) in a lake, so that the reflected rays are completely polarised in a plane parallel to the surface ?

A

`37^(@)`

B

`50^(@)`

C

`72^(@)`

D

`67^(@)`

Text Solution

Verified by Experts

The correct Answer is:
A
`i_p=tan^(-1)(1.33)=53^(@)`
`:.` Angle made by the rays with the surface of water `=90^(@)-53^(@)=37^(@)`
