Pipe A is open at both ends and has length LA. Pipe B is closed at one end and open at the other and has length LB. When both pipes produce sound in their second overtones, the result is a beat frequency of 2.5 Hz. a. Make a careful sketch of the standing wave pattern for the air displacement for each pipe. Next to each sketch write the wavelength for each pipe in terms of the pipe lengths LA...

Pipe A, which is 2.40 m long and open at both ends, oscillates at its third lowest harmonic frequency. It is filled with air for which the speed of sound is 343 m/s. Pipe B, which is closed at one end, oscillates at its second lowest harmonic frequency. This frequency of B happens to match the frequency of A. An x axis extends along the interior of B, with x = O at the closed end. (a) How many nodes...
