Problem

Two polarisers

P_1

and

P_2

are placed in such a way that the intensity of the transmitted light will be zero. A third polariser

P_3

is inserted in between

P_1

and

P_2

, at the particular angle between

P_2

and

P_3

. The transmitted intensity of the light passing through all three polarisers is maximum. The angle between the polarisers

P_2

and

P_3

is: [April 4, 2025 (II)] (a)

\frac{\pi}{4}

(b)

\frac{\pi}{6}

(c)

\frac{\pi}{8}

(d)

\frac{\pi}{3}
