A plane polarized light is incident normally on a tourmaline plate. Its E vector make an angle of `60^(@)` with the optic axis of the plate. Find the percentage difference between initial and final intensities

A

0.25

B

0.5

C

0.75

D

0.9

Text Solution

Verified by Experts

The correct Answer is:
C

`I= I_(0) cos^(2)60^(@)= (I_(0))/(4)`
Change= `I_(0)-(I_(0))/(4)= (3I_(0))/(4) `
% Change = 75%
