Question 181: Waves Optics

Question

When an unpolarized light of intensity $${{I_0}}$$ is incident on a polarizing sheet, the intensity of the light which does not get transmitted is

Accepted Answer

$$I = {I_0}{\cos ^2}	heta $$
Intensity of polarized light $$ = {{{I_0}} \over 2}$$
$$ \Rightarrow $$ Intensity of untransmitted light $$ = {I_0} - {{{I_0}} \over 2} = {{{I_0}} \over 2}$$

Answer

$${1 \over 4}\,{I_0}$$

Answer

$${1 \over 2}\,{I_0}$$

Answer

$${I_0}$$

Answer

zero
