- This Wave Motion Apparatus demonstrates the form and propagation of longitudinal and transverse waves.
- It rotates a set of cams that raise and lower 24 vertical rods with plastic highlighted tips for easy viewing.
- It measures 480mm long, is sturdy, and operates almost silently.
- Eight of the rods are positioned at 90 degrees to simulate transverse wave motion. The handle features a circular scale marked in degrees of rotation.
