1. The problem statement, all variables and given/known data It is observed that a tube open at both ends exhibits harmonics at 438 Hz, 584 Hz, and 730 Hz. A) Calculate the fundamental overtone of the tube. B) Calculate the length of the tube. 2. Relevant equations L=lambda/2 x n, v = f x lambda 3. The attempt at a solution I know that the fundamental overtone is the second harmonic so n would be 2 but to calculate the frequency I would need to know the velocity and wavelength and I don't see how I can get those.
