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?
