Two poloroids $\displaystyle P_1$ and $\displaystyle P_2$ are placed parallel to each other with common axis. The light of intensity $\displaystyle I_0$ passes through a polaroid sheet $\displaystyle P_1$ and then passes through polaroid $\displaystyle \mathrm{P}_2$. If $\displaystyle \mathrm{P}_2$ is now rotated by $\displaystyle 60$°, then the intensity of the output light from $\displaystyle \mathrm{P}_2$ will be:
Official answer
(4)
$\displaystyle \frac{I_0}{8}$
