An unpolarized beam of light of intensity `I_(0)` passes through two linear polarizers making an angle of `30^(@)` with respect to each other. The emergent beam will have an intensity –

A

`(3I_(0))/(4)`

B

`(sqrt(3)I_(0))/(4)`

C

`(3I_(0))/(8)`

D

`(I_(0))/(8)`

Text Solution

Verified by Experts

The correct Answer is:
C
`((I_(0))/(2))cos^(2)30^(@)= (I_(0))/(2)((3)/(4))`
Final intensity will be `= (3I_(0))/(8)`
