Unpolarised light beam of intensity I(0)...


Unpolarised light beam of intensity `I_(0)` is incident on polaroid `P_(1)`. The three polaroids are arranged in such a way that transmission axis of `P_(1)` and `P_(3)` are perpendicular to each other. Angle between the trasmission axis of `P_(2)` and `P_(3)` `60^(@)`. The intensity of the beam coming out from `P_(3)` will be:

A

`(I_(0))/(2)`

B

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

C

`(3I_(0))/(32)`

D

`(3I_(0))/(64)`
