367851 Unpolarised light of intenisty \(I\) is incident on a sypstem of two polarizers, \(A\) followed by \(B\). The intenisty of emergent light is \(I/2\). If a third polarizer \(C\) is placed between \(A\) and \(B\) the intensity of emergent light is reduced to \(I/3\). The angle between the polarizers \(A\) and \(C\) is then

1 \(\cos \theta=\left(\dfrac{2}{3}\right)^{1 / 4}\)
2 \(\cos \theta=\left(\dfrac{1}{3}\right)^{1 / 4}\)
