Purpose: To demonstrate several harmonics of standing longitudinal waves.

*Demonstration not currently available in CHEMP 130. Use W10 as a substitute.

If you need this demo sooner rather than later let me know and I'll move its priority up.

Stretched slinky supported at several points along its length.

Gently shake a support near one end of the slinky. When you find the right frequency, a standing wave will result with very little input energy. Vary the frequency to produce other harmonics.

Note: Practice is needed to get good results.
