Varnished wood, with movable piston marked with the chromatic scale from C (512) to (1024). Overall length when fully extended 840mm. May be used for investing the phenomenon of beats in conjunction with a second pipe of the same type.
Vibrations within an organ pipe produce sound waves. Loud tones can be produced by blowing on the organ pipes or connecting them through a rubber hose to the air supply faucet. Three different tones are available and one wooden pipe with sliding piston. The resonant cavity's length can be varied to provide tones of varying pitch. In conjunction with a microphone, amplifier, and oscilloscope, the relationship between wave frequency and tone can be investigated.
