The fundamental frequency imposed on the jet is determined by the length of the pipe and the speed of sound, that is the time that it takes for each compression/rarefaction event initiated by the jet to transit the length of the pipe.
The question is the energy source to drive the harmonic frequencies. If the jet flicks in and out of the organ pipe, adding energy only while flicking into the pipe, and if the fundamental frequency of the pipe were 110 Hz, then during each second there are one hundred and ten 4.5 ms gaps during...
Homework Statement
Organ pipe sound is driven by a compressed air jet flicking alternately in and out of the pipe in step with the fundamental frequency. My question is whether sound waves of the higher frequency harmonic series are emitted during the intervals when the jet is outside of the...
