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:

Options

A. `(I_(0))/(2)`
B. `(3I_(0))/(8)`
C. `(3I_(0))/(32)`
D. `(3I_(0))/(64)`

Answer

C
