1. The problem statement, all variables and given/known data An experiment was conducted with a string. the following successive harmonics were measured: 46.9Hz, 53.7Hz, 61.9Hz, 70.9Hz a. Evaluate the fundemental frequency b. which harmonic corresponds to the 61.9Hz frequency? 2. Relevant equations 3. The attempt at a solution Well, on average the gaps between the harmonics are 8Hz, so it looks like they are all multiplies of 8Hz (on average). But I don't know if its a string with two fixed points or not, because the fundemental is different in each case.
