What should be the angle between the axes of the polarizer, so that the intensity of the beam coming out of analyzer is 3/8 I
45 degree
30 degree
60 degree
cos-1(3/8) rad
When unpolarized light is passed through the polarizer the intensity becomes half, Hence after passing through polarizer equals
Now after coming out of the analyzer, the intensity becomes
Use Malus Law,
Option (2) is correct.
