The polaroids are placed in the path of unpolarized beam of intensity

1.	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 beA. `((I_(0))/(8))sin^(2)2theta`B. `((I_(0))/(4))sin^(2)2theta`C. `((I_(0))/(2))cos^(2)theta`D. `I_(0)cos^(4)theta`
Answer» Correct Answer - A `I = (I_(0))/(2)cos^(2)theta`
