  1. 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?
  2. Calculate the final intensity of the transmitted beam if ϴ1= 15°, ϴ2 = 40°, and ϴ3 = 82°.
  3. What would the answer to (b) be if the incident beam were unpolarized, but had the same initial intensity?
  4. What is the angle of polarization of the light traveling between the second and third polarizers? State your answer as an angle measured from the vertical.
  5. Now imagine adding a fourth polarizer. At what angle should you orient the axis of the fourth polarizer to completely cancel out the light exiting from the third polarizer? State your answer as an angle measured from the vertical.
