Two Nicols are oriented with their principal planes making an angle of `60^@`. The percentage of incident unpolarised light which passes through the system is

A

0.5

B

1

C

`12.5%`

D

`37.5%`

Text Solution

Verified by Experts

The correct Answer is:
C

`I = (I_(0))/(2) cos^(2) theta`
`(I)/(I_(0)) = (1)/(2) cos^(2) 60 = (1)/(8) = 0.125 = 12.5%`
