Two polaroids $P_1$ and $P_2$ are set in crossed positions. A third polaroid $P_3$ is placed between the two making an angle $α$ with the axis passing from the first polaroid $P_1$. In what orientation will the transmitted intensity be maximum?

$\frac{π}{2}$ $\frac{π}{3}$ $\frac{π}{4}$ 0

$\frac{π}{4}$

The correct answer is Option (3) → $\frac{π}{4}$
