Unpolarized light of intensity 32 W m -2 passes through three polarize such that transmission axis of first is crossed with third. If intensity of emerging light is 2W m -2 . what is the angle of transmission axis between the first two polarisers?
Text Solution
Verified by ExpertsThe correct answer is:
C
Let 
be angle between the axis of the first two polarizer’s then obviously 
is the angle between 2 nd and 3 rd polariers.
