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 polaroids then the intensity of light emerging from the last polaroid will be :
\[\left( \frac{I_{0}}{8} \right)sin^{2} 2\theta\]
\[\left( \frac{I_{0}}{4} \right)sin^{2} 2\theta\]
\[\left( \frac{I_{0}}{2} \right)cos^{2} \theta\]
\[I_{0}cos^{4} \theta\]
