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

`50%`

B

`100%`

C

`12.5%`

D

`37.5%`

Text Solution

Verified by Experts

The correct Answer is:
C
Intensity of polarised light from first polariser
`=100/2=50`
`l=l_(0)cos^(2)theta=50cos^(2)60^(@)`
`=50/4=12.5`
