Experiment 2:
Resonance Tubes
Introduction
In this experiment you will discover the relationship between the wavelength, wave speed and
frequency of sound waves in resonance tubes. You will learn about nodes, anti-nodes and the end
effect in both closed and open tubes.
Set-up
1.
Turn on the Sine Wave Generator and turn the amplitude knob all the way down (counter-
clockwise).
2.
Connect the generator to the speaker using two banana patch cords. Polarity does not matter.
3.
Place the Resonance Tube horizontally, as shown, with the speaker near the open end. Place
the speaker at a 45° angle to the end of the tube, not pointed directly into it.
