(C) According to Malus's law,the intensity of polarized light transmitted through a polarizer is given by the formula:$I = I_0 \cos^2 	heta$where $I_0$ is the intensity of the incident polarized light,$	heta$ is the angle between the pass axis of the polarizer and the plane of polarization of the incident light.Given:$I_0 = I_0$$	heta = 60^o$Substituting the values into the formula:$I = I_0 \cos^2(60^o)$Since $\cos(60^o) = \frac{1}{2}$,we have:$I = I_0 \left(\frac{1}{2}ight)^2$$I = I_0 \left(\frac{1}{4}ight)$$I = \frac{I_0}{4}$Therefore,the intensity of the emergent polarized light is $\frac{I_0}{4}$.

$A$. Angle of reflection	$(i)$ $2 \sin^{-1} \left(\sqrt{\frac{2}{3}}\right)$
$B$. Angle of refraction	$(ii)$ $\sin^{-1} \left(\sqrt{\frac{2}{3}}\right) - \sin^{-1} \left(\frac{1}{\sqrt{3}}\right)$
$C$. Angle between incident and completely polarised light	$(iii)$ $\sin^{-1} \left(\frac{1}{\sqrt{3}}\right)$
$D$. Angle of deviation of the incident ray	$(iv)$ $\cos^{-1} \left(\frac{1}{\sqrt{3}}\right)$

$A$ polarized light of intensity $I_0$ is passed through another polarizer whose pass axis makes an angle of $60^o$ with the pass axis of the former. What is the intensity of emergent polarized light from the second polarizer?

Explain Malus's law and state its mathematical expression.

An unpolarised light beam of intensity $2 I_{0}$ is passed through a polaroid $P$ and then through another polaroid $Q$ which is oriented in such a way that its passing axis makes an angle of $30^{\circ}$ relative to that of $P$. The intensity of the emergent light is.
