The seventh harmonic of a one end closed pipe organ has a frequency of 732 Hz, on a day when the temperature is 10 degrees Celsius. How long is the pipe? How long would it be for 732 to be the first harmonic?
speed of sound in air at atmosphere
v = 331 m/s + (0.6 m/s/C)•T
v=wavelength * Frequency
=> wavelength= v/Frequency = 0.46 m if 732 were first harmonic
=> Length being 7th harmonic
= 7 * 0.46 m = 3.22 m
