A ray of light is incident on the surface of plate of glass of refractive index `1.5` at the polarising angle. The angle of refraction of the ray will be

A

`75^(@)11`'

B

`32^(@)50`'

C

`147^(@)11`'

D

`0^(@)`

Text Solution

Verified by Experts

The correct Answer is:
B
`tani_(p)=mu=1.55impliesi_(p)=tan^(-1)(1.55)=57^(@)10`
`r=90^(@)-i_(p)=90^(@)-57^(@)10.=32^(@)50.`
