Wave Motion Apparatus

Wave Motion Apparatus

Product Code : SCL-SSLDK-11513

Quick Answer: The Wave Motion Apparatus is a hand-cranked mechanical wave generator in which a row of vertical rods moves in sequence to model the motion of particles in a wave. It demonstrates both transverse and longitudinal waves.

Last updated: October 2026

Key Features

  • Row of vertical rods driven in a coordinated sequence by a hand crank
  • Shows transverse and longitudinal waves in a single frame
  • Crank speed is set by hand, changing the wave frequency
  • Makes peaks, troughs and compressions visible to a whole class

About This Product

Turning the handle sets the rods moving so students can see frequency, amplitude, wavelength and phase difference as a physical pattern. Comparing the two wave types side by side shows how particles vibrate across or along the direction of travel, and changing the crank speed links frequency to wave energy.

Frequently Asked Questions

Can the Wave Motion Apparatus show both kinds of wave?

Yes. It demonstrates both transverse and longitudinal wave patterns in a single mechanical frame, driven by a hand crank.

How is the wave frequency changed?

By turning the hand crank faster or slower; the manual speed sets the frequency of the wave shown.
