ID Code: H3-17
Purpose: Demonstrates standing waves in a tube
Description: A loudspeaker in one end of a four-inch diameter galvanized iron tube creates standing waves in propane gas in the tube. The gas emerges out of a series of small holes in the top of the tube, forming a long line of flames when lit. Any sound resonant with the length of the tube can create standing waves in the gas which are readily visible as a pattern in the height of the flames. Both rhythm and frequency response can be seen nicely in music. An oscillator or a voice introduced using a microphone and amplifier provided with the demonstration can be used as simple sources for the loudspeaker.
