Complete Wave Motion Demonstrator

Product Code: SE-9600

Description

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


Features

  • 2.3 Meters Long: Plenty of room to watch the wave develop and interact.
  • Three Wave Sections: Each section has rods of different lengths, allowing reflection and transmission demonstrations.
  • Section 1 is 92 cm long with 46 cm rods.
  • Section 2 is 92 cm long with 23 cm rods. The resulting wave velocity is three times as fast.
  • Section 3 is 46 cm long with rods that vary exponentially from 46 cm to 23 cm. This section acts as an impedance-matching unit.
  • Yellow Rod Tips: For easy viewing and to highlight the wave motion.

Demonstrate

  • 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
  • Wave Propagation

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 inertia of the rods.
