Two polaroids are placed in the path of unpolarized 16 beam of intensity I such that no light is emitted from the second polaroid If a third polaroid whose polarization axis makes an angle with the polarization axis of first polaroid is placed between these polaroids then the intensity of light emerging from the last polaroid will be 1 4 8 sin 220 Io 3 1 cos 0 COS 2 7 4 4 Incos 0 2 sin 20
