An organ pipe is open at one end and closed at the other. The pipe is 1.5 m long. Assume the speed of sound in the pipe is 340 m/s. The lowest harmonic frequency for this pipe is ________Hz.
A) A hole is drilled in the side of the pipe 0.5 m from the closed end, fixing the pressure at this point to atmospheric pressure.
B) Determine the new lowest harmonic frequency in the pipe. _________Hz
C) Explain how the principle of this problem applies to woodwind instruments like the flute and recorder.
