3B22.30 - Wave Demo - Wave Machines

Code Number:
Demo Title:
Wave Demo - Wave Machines
Wave Motion
Area of Study:
Acoustics, E & M
Wave Machines (4) (Crank Models), Wave Machines (Wire Models with Accessories).

Set the wire machines up as shown and connect the water damper and counter balance.  This is to help damp out the reflecting wave which is unwanted most of the time.

The hand crank wave machines will need periodic oiling, adjusting, and painting of the moving parts.
