Add to order
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 absorb-o-matic device at right in photographs above to prevent reflection at the other end of the machine. 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: Available. (PIRA 3B22.30)
EQUIPMENT: Shive Wave Machine with absorber.
SETUP TIME: 10 minutes.
