A
beam of unpolarized light is incident on a stack of four polarizing
sheets that are lined up so that characteristic direction of each is
rotated by
|

Let the
intensity of the unpolarized incident beam be
The incident of the beam after it emerges from the first polarizing sheet will become
As the
characteristic directions of each successive three polarizing sheets
are rotated by
|
clockwise with respect to the preceding sheet.
We have to find the fraction of the incident
intensity that is transmitted.
