Additional Info

• ID Code: H3-42
• Purpose: Demonstrate the resonance behavior of open and closed tubes.
• Description: A tube is excited by an oscillator driving a small loudspeaker. The sound is picked up by a sound probe adjacent to the driven end of the tube, and displayed on the oscilloscope. Resonances are clearly observable on the oscilloscope. The closed tube is obtained by placing a cap on the left end of the open tube shown in the photograph.

  These are the same tubes used in H3-24. Consider showing them to students first and having them make predictions, then using this apparatus to analyze the results.
