Question
A beam of unpolarised light of intensity Io is passed through a polaroid A and then through another polaroid B which is oriented so that its principal plane makes an angle of 45o relative to that of A. The intensity of the emergent light is :-
Options
A.I0
B.I0/2
C.I0/4
D.I0/8
Solution
Since the incident light is unpolarized, intensity after light passes through polaroid A is 
After this light passes through B,
