Two polaroids are placed in the path of unpolarised beam of intensity 
such that no light is emitted from the second polaroid. If a third polaroid whose polarization axis makes an angle 
with the polarization axis of first polaroid, is placed between these polaroids then the intensity of light emerging from the last polaroid will be

(a)
No light is emitted from the second polaroid, so 
and 
are perpendicular to each other

Let the initial intensity of light is 
. So Intensity of light after transmission from first polaroid 
Intensity of light emitted from 
Intensity of light transmitted from last polaroid 
from
