ID Code: M1-14
Purpose: Demonstrate interference using microwaves.
Description: Two identical transmitting antennas for microwaves (shiny strips mounted on meter stick) are driven by the same source, creating two coherent sources. Scanning the region in front of the two sources reveals an interference pattern, which can be seen by a class using a projection meter connected to the microwave receiver.

The photograph at the left shows the receiving antenna at the central maximum; at the right the receiving antenna is at the first minimum.
