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)((sqrt3)/(2))`

B

`cos^(-1)((sqrt3)/(2))`

C

`tan^(-1)((sqrt3)/(2))`

D

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

Verified by Experts

The correct Answer is:

D

`mu=tanphi=tan60^(@)=sqrt3" for polarization"`.
`"For critical angle ",mu=(1)/(sinC) implies sinC=1/(sqrt3)`
`implies" " C=sin^(-1)(1/(sqrt3))`
