The original idea for this can be found on the internet in a variety of places. Personally I got this implementation from Don Pata. The music I use was composed and performed by some of my students.

Falconphysics Democast - Interference and Standing Waves

Wed, 30 Sep 2009 11:07:49 +0000

InterferenceTwo waves or pulses in the same place at the same time combine and appear to be a single wave or pulse. The waves continue on unchanged by the interaction in the direction of propagation (i.e. the direction they were traveling).Constructive interference happens when the resulting amplitude is larger.Destructive interference happens when the resulting amplitude is smaller. In some cases there is Complete Destructive interference where there is no sign of a wave or pulse passing.
