PURPOSE: To demonstrate traveling waves.
DESCRIPTION: Make sinusoidal waves by moving the spines at one end of the machine up and down sinusoidally, either with your hand or using the wave generator. Vary the amplitude and the frequency and observe the wavelength. Show semi-quantitatively that the wave speed is the same for all frequencies.
SUGGESTIONS: Use dashpot to prevent reflection at the other end of the machine.
REFERENCES: (PIRA 3B22.30)See Demonstration Reference File for further information and experiments.
EQUIPMENT: Shive Wave Machine with dashpot.
SETUP TIME: None.
