Info

A mechanical driver with two knobs sends ripples through water in shallow tank, and an overhead projector projects this image onto the screen. The relative phase and the frequency of the two knobs can be varied; in addition there is an assortment of one slit and two slit apertures as well as concave and convex reflectors that can be placed in the water.

Note: Ask what professor wants to demo to give the right bobs. Tank should be high enough so the overhead can slide underneath it. This can all be set up and left on a rolling table. Long setup time.
