Homework Answers
a) Let initial intensity = Io
After one polarizer = Io/2
Final intensity = I = Io/2*cos^2 60 = 0.125*Io
b) I = 0.125*Io*cos^2 45 = 0.0625*Io

The diagram below shows a beam of light shining through three
linear polarizers in a row. The polarizing axis of each polarizer
is measured at an angle (ϴ1,ϴ2,ϴ3) from vertical.
Suppose that the original beam of light emanates from a
vertically polarized laser. The laser has a power output of 1 mW
and the beam has a diameter of 2 mm. What is the intensity of the
laser beam before it travels through any polarizers?
