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
`mu=tan p=tan 60^(@)=sqrt(3)`
`sin C=1/mu=1/sqrt(3) implies C=sin^(-1)(1/sqrt(3))`
