1. The problem statement, all variables and given/known data A pipe, open at one end, has a leng produces pipe A, open at one end, and pipe B, o A pipe, open at one end, has a length L. Cutting this pipe crosswise produces pipe A, open at one end, and pipe B, open at both ends. a. For what length of pipe A will the third lowest resonant frequency of pipe A be equal to the lowest resonant frequency of pipe B? 2. Relevant equations v = (lambda)(f) 5th harmonic of A, f = (5v)/(4L) 1st Harmonic of B, f = v/2L 3. The attempt at a solution I've been fairly stumped by this one. I don't get exactly how to set it up. I tried setting the frequencies equal to each other, but it doesn't work.
