A transparent thin plate of a polaroid is placed on another similar plate such that the angle between their axes is 
. The intensities of the emergent and the unpolarized incident light will be in the ratio of
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
D
Let 
be the intensity of unpolarized light, then intensity of light from first transparent thin plate of a polaroid is
Now this light will pass through the second similar plate whose axis is inclined at an angle of 
to that of first plate.
According to Malus law, the intensity of emerging light is
