Pipe Organ62

  1. Jan 21, 2007 #1
    1. The problem statement, all variables and given/known data

    A pipe organ playing in a concert produces a 440 Hz signal with a pipe open at both ends.if the ideal temperature is 20degrees, what is the length of the pipe(first harmonic)

    2. Relevant equations
    f=N/T
    f=1/T
    v=f*wavelength
    sound equation

    3. The attempt at a solution

    332ms*0.59*20
    =332ms+0.118ms
    =332.118ms
    i dont know where to go from there

    You know the velocity of sound at 20 degrees C (at least I hope you have the right equation) and you know the frequency. Its simply a matter of rearranging this v=f*wavelength for wavelength.

    Also remember that the first harmonic in an open pipe has a wavelength of twice the pipes length.
