Two polaroids are placed in the path of unpolarised beam of intensity I0 such that no light is emitted from the second polarioid. 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 :
\[\frac{I_{0}}{8}sin^{2} 2\theta\]
\[\frac{I_{0}}{4}sin^{2} 2\theta\]
\[\frac{I_{0}}{2}cos^{4} \theta\]
\[I_{0}cos^{4} \theta\]
