The polarising angle the transparent medium is `'theta'` and 'v' is the speed of light in that medium. Then the relation between `'theta'` and 'v' is
(c = velocity of light in air)

A

`theta=tan^(-1) ((v)/(c))`

B

`theta=cot^(-1) ((v)/(c))`

C

`theta=sin^(-1) ((v)/(c))`

D

`theta=cos^(-1)((v)/(c))`

Text Solution

Verified by Experts

The correct Answer is:
B
`therefore tan theta=mu=(C)/(V)`
`therefore cot theta=(V)/(C)`
`therefore theta=cot^(-1) ((V)/(C))`
