    Unpolarized light with intensity I0I_0 passes through three polaroids such that the transmission axis of the last polaroid is crossed with the first. If the intensity of emerging light is I1(I1=332I0)I_1\left(I_1 = \dfrac{3}{32}I_0\right). The angle between the first two polaroids and the angle for which the transmitted intensity is maximum are respectively {\{given, cos⁡(90)=0}\cos(90) = 0\}
