Two ideal polaroids are placed in the path of unpolarized beam of light of intensity I0, such that intensity of the emerging light is found to be I0∕2. If a third polaroid whose polarization axis makes an angle ‘θ’ with the polarization axis of first polaroid, is placed between these two polaroids, then the intensity of light emerging from the last polaroid will be-
