Transverse Wave Pendulum Apparatus
Product Code : SCL-PLE-11639
Quick Answer: The Transverse Wave Pendulum Apparatus, also called a wave machine, is a row of independent pendulums with filaments of different lengths on a 450mm x 150mm x 300mm frame; released together, their swings drift out of step and form a moving sinusoidal wave.

Key Features
- Row of independent pendulums with high-visibility bobs.
- Variable-length suspension filaments.
- Metal or reinforced polymer support frame.
- Pendulums set in a straight horizontal line for transverse displacement.
Technical Specifications
| Specification | Value |
|---|---|
| Pendulums | Series of independent pendulums, high-visibility bobs |
| Suspension | Variable-length filaments |
| Frame | Metal or reinforced polymer |
| Layout | Linear, horizontal row |
| Dimensions | 450mm x 150mm x 300mm |
How It Is Used
All the bobs are pulled aside together and released. Because each pendulum has a different length, and so a different period, the row drifts out of step and a sinusoidal wave seems to travel along it before the pattern reforms. It links simple harmonic motion, T = 2π√(L/g), with the idea of phase in a wave.
Frequently Asked Questions
Why do the pendulums of the Transverse Wave Pendulum Apparatus form a wave?
Each filament length gives its pendulum a different period. Released together, the pendulums fall gradually out of phase, and the changing phase along the row appears as a transverse wave.
