- Purpose
- To demonstrate the action of traveling longitudinal waves.
- Location
- room 146, shelf O2
- Description
- When the knob on the right is rotated clockwise, compressions and rarefactions appear to travel across the model. But the individual �particles� (i.e. slats) do not �travel�, but simply oscillate about an equilibrium position. The �traveling� motion is a result of phase differences between the oscillations of neighboring �particles�.
