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
`tantheta_(b)= n`
`implies n= tan60^(@)= sqrt(3)`
Critical angle
`i_(c)= sin^(-1)((1)/(n))= sin^(-1)((1)/(sqrt(3)))`
