A beam of unpolarised light is passed first through tourmaline crystal A and then through another tourmaline crystal B oriented so that its principal plane is parallel to that of A. The intensity of the emergent light is I. If A now rotated by 45∘ in a plane perpendicular to the direction of the incident ray, the intensity of the emergent light will be

Two polaroids are placed in the path of unpolarized beam of intensity I0 such that no light is emitted from the second polaroid. If a third polaroid whose polarization axis makes an angle θ with the polarization axis of first polaroid, is placed between these polariods then the intensity of light emerging from the last polaroid will be.
