For given medium, the polarising angle is `60^(@)`. What will be the critical angle for this medium ?

A

`35^(@)16'`

B

`42^(@) 22'`

C

`57^(@)`

D

`60^(@)`

Text Solution

Verified by Experts

The correct Answer is:
A
`mu = tan theta_(P) = (1)/(sin c)`
`:. sin c = (1)/(tan 60) = 0.5773`
`:. c = 35^(@)16'`
