PURPOSE: To demonstrate standing waves.

DESCRIPTION: Standing waves can be generated with either (1) both ends fixed (set at left), (2) one end fixed and one end free (set at right), or (3) both ends free (set in center). Either use your hand or the motorized drive; your hand possesses better feedback for small adjustments in frequency. A metronome is available for comparing the frequencies of various harmonics.

SUGGESTIONS: The manual written by Shive contains excellent information on both the theory and the use of the wave machine; copies are available in the Lecture-Demonstration office.

REFERENCES: (PIRA 3B22.30)See Demonstration Reference File for further information and experiments.

EQUIPMENT: Shive Wave Machine with clamp; driver and metronome upon request.

SETUP TIME: None.
