Three polaroid sheets are kept parallel to each other such that first and last are crossed. Unpolarised light of intensity 32 Wm ⁻² falls normally on the first sheet and passes through all the polaroid sheets. If the intensity of the emerging light from the third sheet is 3 Wm ⁻² , then the angle between the axes of the first two polaroid sheets is
