Physics - Wave Optics Question with Solution | TestHub

As shown in figures, three identical polaroids ${\mathrm{P}}_1$, $P_2$ and $P_3$ are placed one after another as shown in figure. The pass axis of ${\mathrm{P}}_2$ and ${\mathrm{P}}_3$ are inclined at angle of $30^{\circ }$ and $90^{\circ }$ with respect to axis of ${\mathrm{P}}_1$. The source S has an intensity of $288\mathrm{W}/{\mathrm{m}}^2$. The intensity of light after passing through polaroids ${\mathrm{P}}_3$ is $\_\_\_\_$ $\mathrm{W}/{\mathrm{m}}^2$.
