Question

An open organ pipe has a fundamental frequency of 300 Hz. The third harmonic of a closed organ pipe has the same frequency as the second harmonic of the open pipe. How long is each pipe? [speed of sound in air = 340 m/s]

Answer 1

For an open organ pipe, ν = v/λ = v/2l 1 for fundamental frequency (n = 1) without endcorrection.
