Resonance Tube and Wave Generator
Resonance Tube and Wave Generator

 

Code Number: 3D30.16

Demo Title: Resonance Tubes - Sliding Piston

Condition: Excellent

Principle: Resonance in Pipes

Area of Study: Oscillations & Acoustics

Equipment: 

Resonance Tube and Wave Generator.

Procedure:

Plug the wave generator into the speaker that is mounted at one end of the tube.  Slide the movable piston back and forth until the sound of the speaker becomes louder.  This position should be 1/2 wave length as measured by the scale attached to the tube.
