Code Number: 6H10.20
Demo Title: Polarization - Microwave
Condition: Excellent
Principle: Polarization of Light
Area of Study: Optics, E & M
Equipment:
Microwave Generator and Receiver, Amplifier and Speaker, and Metal Gratings.
Procedure:
The microwave demo is assembled as usual. Between the generator and receiver place the metal gratings. By turning the grating 90 degrees you can show that the signal is polarized.
