Additional Info

• ID Code: m9-23
• Purpose: Demonstrate properties of circularly polarized light.
• Description: Light from a bright point source with condenser and iris passes through a yellow filter and two crossed polaroids onto a distant screen. When the polarizer and analyzer are crossed and the quarter-wave plate is set at 45 degrees, rotating the analyzer does not produce any changes in the intensity of the beam. This is the effect of circular polarization.
