The angle of polarisation for any medium...

The angle of polarisation for any medium is `60^(@)` , what will be critical angle for this

A

`sin^(-1)sqrt(3)`

B

`tan^(-1)sqrt(3)`

C

`cos^(-1)sqrt(3)`

D

`sin^(-1)1/sqrt(3)`

Text Solution

Verified by Experts

The correct Answer is:
D
By using `mu= tan theta_(p)`
`rArrmu=tan60^(@)=sqrt(3)`
Also `C=sin^(-1)(1/mu)rArrC=sin^(-1)(1/sqrt(3))`
