Q1

Two polaroids \(A\) and \(B\) are placed in such a way that the pass-axis of polaroids are perpendicular to each other. Now, another polaroid \(C\) is placed between \(A\) and \(B\) bisecting the angle between them. If intensity of unpolarised light is \(I_0\) then intensity of transmitted light after passing through polaroid B will be:

a

\(
\frac{I_0}{4}
\)

b

\(
\frac{I_0}{2}
\)

c

\(
\frac{I_0}{8}
\)

d

\(
\text { Zero }
\)
