Resonance question

  1. Sep 11, 2010 #1
    I don't want the answer to this problem just an idea of how to get started. I don't understand what I am looking for. Thanks.

    1. The problem statement, all variables and given/known data

    A 143-cm-long pipe is stopped at one end. Near the open end, there is a loudspeaker that is driven by an audio oscillator whose frequency can be varied from 10.0 to 4700 Hz. (Take the speed of sound to be 343 m/s.)

    2. Relevant equations
    freq= v / λ (just guessing)

    3. The attempt at a solution

    I don't understand what you are looking for either. There is no question attached to the statement of the situation, but f = v/λ is correct regardless.

    I presume you want to find the resonant frequency of the pipe. Let's narrow it down a bit. Will it be when the length of the pipe is equal to 1/4 wavelength, 1/2 wavelength or 1 wavelength of the frequency?
