 optical bench
 rod, 10 cm
 lamp
 several riders
 convex lens,
Material needed: f= 50mm
 convex lens, f= 100mm
 aperture with a hole
(d=8mm)
 2 polarizing filters
 screen
 power supply
1. Label the sketch of your experimental setup.
2. At first, the two polarizing filters should be equally oriented. Then turn the analyzer slowly around 360° and describe your observations.
3. At what angle of rotation does maximum/minimum brightness occur?
4. Explain the result including some theoretical facts about polarization (You can use the internet – e.g. http://www.colorado.edu/physics/2000/polarization/index.html).
