The polariser and analyser are inclined ...

The polariser and analyser are inclined to each other at `60^(@)`. The intensity of polarised light emerging from polariser is I. The intensity of the unpolarised light incident on the polariser is

A

I

B

8I

C

4I

D

2I

Text Solution

Verified by Experts

The correct Answer is:
B
`I = (I_(0))/(2) cos^(2) theta = (I_(0))/(2) cos^(2) 60 = (I_(0))/(2) xx (1)/(4)`
`:. I_(0) = 8 I`
