The axes of the polariser and analyser are inclined to each other at `60^(@)`. If the amplitude of polarised light emergent through analyser is A. The amplitude of unpolarised light incident polariser is

A

`(A)/(2)`

B

A

C

2A

D

`2 sqrt(2) A`

Text Solution

Verified by Experts

The correct Answer is:
D
`A_(1)= A_(0) cos 45 = (A_(0))/(sqrt(2)) , A_(2) = (A)/(sqrt(2)) cos theta`
