^ denotes power
Let the intensity of unpolarized light be I
Then the intensity of light beyond the first polaroid sheet will be I / 2.
If we denote this intensity by I1 then I1= I /2
(This is because in the incident unpolarized light the amplitude of the electric vectors parallel to the the axis of the first polaroid ...
