A transparent medium shows relation between i and r as shown. If the speed of light in vacuum is c, the Brewster's angle for the medium is

A

`60^@`

B

`30^@`

C

`90^@`

D

`45^@`

Text Solution

Verified by Experts

The correct Answer is:
A
slope of the graph is `((1)/(n))`
So` ( sin r )/( sin I ) = (1)/(n) = tan 30^@ `
` n sqrt(3) `
` n= tan theta_p implies theta_p = 60^@`
