Two polariods are oriented with their transmision axes making angle of `30^(@)` with each other. The fraction of incident un polarised light is transmitted

A

`37%`

B

`37 . 5 %`

C

`3 . 36%`

D

`36 . 5%`

Text Solution

Verified by Experts

The correct Answer is:
B
`I_(1) = (I_(0))/(2), I_(2) = I_(1) cos ^(2) theta , ` Fraction `(I_(2))/(I_(0)) = (3)/(8)`
