Polarisation

Question

The amplitude of polarised light transmitted through a polariser is A. The amplitude of unpolarised light incident on it is

Moderate

A

$\frac{A}{2}\$
B

$\frac{A}{{\sqrt 2 }}\$
C

2A
D

$\sqrt 2 A\$

Solution

$A = \frac{{{A_0}}}{{\sqrt 2 }} \Rightarrow {A_0} = \sqrt 2 A\$
$as{\text{ }}I = \frac{{{I_0}}}{2}and\,;I\alpha {A^2}\,;{I_0}\alpha A_0^2\$
