Homework Help: Open end resonant length

  1. Dec 3, 2006 #1
    1. The problem statement, all variables and given/known data
    an organ pipe, open at both ends, esonantes ats its 1st resonant lenth with a frequency of 128hz. what is thelength of the pipe if the speed of sound is 346m/s

    2. Relevant equations
    the open colum patterns

    3. The attempt at a solution
    i just cant get it

    From the univeral wave equation, what is the wavelength at the given frequency and wave speed?

    From the open column patterns, how many wavelengths does the length of an open pipe contain? (Hint, the answer is not 1)
