6H 10.10 - Polarization

Demonstrates: Polarization
Description: Use small insert optical bench with the Beseler projector. There are several slides.

6H 10.15 - Polarization with Big Polarizers

Demonstrates: Polarization.
Description: Use Fresnel spotlight and large polarizers.

6H 10.20 - 3 cm Microwave Apparatus

Demonstrates: Polarization and diffraction.
Description: Hold dipole array at 90 degree angle to show polarization. Double and single slits are available for diffraction - swing receiver in an arc ~ 2 meters from slits. An aluminum sheet can be used to show shielding. Interference beats occur when sheet is held parallel to the center line between the transmitter and receiver.

6H 10.40 - Polarization

Demonstrates: Polarization
Description: Second filter detects light polarized by the first filter.

6H 20.10 - Brewster's Angle

Demonstrates: Zero light intensity of a reflected ray at a special angle of incidence.
Description: Light from projector is reflected off glass to give Brewster's angle.

6H 30.10 - 1/4 Wavelength Plates

Demonstrates: Polarization
Description: Two polarizers are set to not allow light through. Then 1/4 wavelength plate is inserted between the polarizers and light reaches screen.

6H 30.40 - Specific Rotation

Demonstrates: Two 1/4 wavelength plates can be used
Description: Sugar dissolved in water will rotate the plane of polarized light.

6H 35.15 - Birefringence

Demonstrates: Polarization with crystals
Description: Incident light is polarized without absorption or reflection by the polarizer.

6H 35.20 - Chromatransparency

Demonstrates: Color change due to polarization
Description: A "transparent" image is placed between two polarizers.
