Wave Machine

Photograph of a wave machine

Apparatus:
wave machine; wave sticks

Description:
wave machine: this demonstration supports itself and is used to show impulse, wave speed and propagation.
wave sticks: this shows the same things as the wave machine, but requires assistants to apply tension. One advantage to this setup is that the wave sticks are assembled as required, and may be made up to specific parameters.
