The relation $I=I_0 \cos ^2 \theta$ is $\left(\mathrm{I}_0\right.$ - Intensity of incident light on the analyser, I intensity of emergent light from the analyser, $\theta$ - angle between plane of polarization and the axis of analyser)

A
Newton's law
B
Snell's law
C
Brewster's law
Correct answer
D
Malus's law

Solution

The relation $I=I_0 \cos ^2 \theta$ is given by Molus's law.

Hence, the correct answer is option: 'D'.
