1. The problem statement, all variables and given/known data A student holds a 325.6 Hz tuning fork near the end of a pipe that is closed at one end. He notices that resonances can be heard for several different lengths, one of which is 55.5 cm. He gradually lengthens the pipe to 92.5 cm where he detects the next resonance. 2. Relevant equations 3. The attempt at a solution Let lamda_1 = 0.555 * 4 = 2.22 m f_1 = 325.6 Hz v = 723 m/s lamda_3 = 4/3 * 0.925 v = 402 m/s Why aren't the two answers consistent?
