Question

An unpolarized light of intensity I 0 passes through three polarizers, such that the transmission axis of last polarizer is perpendicular to that of first. If the intensity of emergent light is 3 I 0 32 and the angle between the transmission axis of first two polarizers is θ , then, θ = 45 °, θ = 37 °, θ = 30 °, θ = 53 °

3 I 0 32 = I 0 2 c o s 2 θ s i n 2 θ 4 cos 2 θ sin 2 θ = 3 4 or sin 2 θ = 3 4 = 3 2 θ = 30 °
