When a polaroid sheet is rotated between two crossed polaroids then the transmitted light intensity will be maximum for a rotation of:
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
D
Let 
be intensity of unpolarised light incident on first polaroid. 
Intensity of light transmitted from 
polaroid 
be the angle between 
and 
polaroid 
be the angle between 
and 
polaroid 
as 
and 
polaroid are crossed)
Intensity from 
polaroid
will be maximum when
