The critical angle of a transparent crys...

The critical angle of a transparent crystal is `60^(@)`. Then its polarizing angle is

A

`cot^(-1)(2)`

B

`cot^(-1)(1/2)`

C

`tan^(-10)(2/(sqrt(3)))`

D

`tan^(-1)((sqrt(3))/2)`

Text Solution

Verified by Experts

The correct Answer is:
C
`sinC=1/(mu)`
`mu=1/(sin60^(@))`
`H=(2/(sqrt(3)))`
`l_(p)=tan^(-1)(mu)`
`I_(p)=tan^(-1)(2/(sqrt(3)))`
