Two polaroids are placed in the path of unpolarized beam of intensity I_(0) such that no light is emitted from the second polarid. If a third polaroid whose polarization axis makes an angle theta with the polarization axis of first polaroid, is placed between these two polariods then the intensity of light emerging from the last polaroid will be

The polaroids are placed in the path of unpolarized beam of intensity I_(0) such that no light is emitted fromthesecond polarid. If a third polaroid whose polarization axis makes an angle theta with the polarization axis of first polaroid, is placed between these4 polariods then the intensity of light emerging from the last polariod will be

Two polaroids are placed in the path of unpolarized beam of intensity I 0 such that the intensity of light emitted from the second polaroid is 9/50 l_(0). If third polaroid whosepolarization axis makes an angle theta with the polarization axis of first polaroid, is placed between these polaroids, such that the intensity of light emerging from the last polaroid is zero, then angle theta is
