K8-11. Microwaves - Standing Waves
Purpose
To demonstrate microwave standing waves.
Equipment
Microwave source, aluminum reflecting sheet, and receiving antenna with projecton meter on overhead projector.
Setup Time
5 minutes.

Description
A standing wave is set up between the source and an aluminum sheet. The receiving antenna can be moved back and forth between the transmitter and the reflector to locate nodes and antinodes. The wavelength is 12 cm, so the nodes (or antinodes) are 6 cm apart.
