Wave Machine

To demonstrate form and propagation of longitudinal and transverse waves. This simple wave demonstrator rotates a set of cams that raise and lower 24 vertical rods with plastic highlighted tips for easy viewing. It is 480 mm long, strong, and almost silent in operation. Lubrication is not required and students can see from both sides. Eight of the rods are turned at 90 degrees to simulate transverse wave motion. The handle is fitted with a circular scale marked in degrees of rotation.
