Lab 3 – The Polarization of Light You are supplied with 3 polarizers, one big on a motorized rotation stage and two little ones that go into standard optical bench holders. 1. Go in the hallway and look at the light reflected off the floor. Is it polarized, and if so, along what direction? Use this effect to calibrate the polarization axis of the two small polarizers with markings on their sides (not the one on the motor). Also, for fun, look at your computer monitor through the polarizer. 2. Using the polarizer that is connected to the stepper motor, measure the degree of polarization of the laser beam by recording the transmitted intensity as a function of polarizer angle. (How should the iris be set for this measurement?) . Verify Malus’ Law your laser. What should the period be and why? 3. Now take the small flash light and put it at the focus point of a converging lens (why?). Use the converging lens with the shortest possible f (why?) (hint: use a piece of paper after the lens and check that the bulb is actually at the focus point
