Introduction 

The Wave Motion Demonstrator allows mechanical waves to be created to demonstrate the behavior and properties common to many types of waves.

How It Works

A series of steel rods is attached at their centers to a torsion wire. When a rod is displaced and released, a wave propagates along the rod. Velocity depends on the torsion constant of the wire and the moment of intertia of the rods.

Wave Demonstration

• Wave Propagation
• Velocity in Different Media
• Wavelength versus Velocity and Frequency
• Reflection at Fixed and Free Boundaries
• Constructive and Destructive Interference
• Standing Waves and Resonance
• Reflection and Transmission at Media Boundaries
