Calculating Resonance Wavelengths

  1. Feb 17, 2010 #1
    1. The problem statement, all variables and given/known data

    Hello all, I am supposed to calculate the resonance wavelength by using the average difference between my measurements of each 1/2 wavelength.

    My data: Frequency = 2501 Hz (s^-1)
    Avg. difference of each 1/2 wavelength = 4.2625 cm
    Length of tube used to perform acoustics = 49.8 cm

    2. Relevant equations

    3. The attempt at a solution

    My problem is that I'm having trouble understanding the question. I don't know how to incorporate the avg difference in order to output the resonance wavelength. Is there a formula?

    Welcome to the PF. I'm not sure I understand the question. How much data did you collect? Based even on just one datapoint, what would you think the resonant wavelength is? Also, based on the speed of sound in air, what would you anticipate for the wavelength of that frequency of sound?
