Resonance tube, Tuning fork, Microphone, Amplifier, and Speaker

 

Code Number: 3D30.10

Demo Title: Resonance Tubes - Water Column

Condition: Excellent

Principle: Resonance in Pipes

Area of Study: Oscillations & Acoustics

Equipment: 

Resonance tube, Tuning fork (384 Hz), Microphone, Amplifier, and Speaker (large).

Procedure:

Fill the movable cup with water.  Place the tuning fork at the top end of the Plexiglas pipe.  Strike the tuning fork and change the water level by moving the cup up or down.  At some point you should find a position where the sound from the tuning fork becomes very loud.  This should be 1/2 wave length and can be measured by the meter stick on the edge of the tube.
