PROBLEMS Standing Waves in Air Columns 1. Organ pipe A, with both ends open, has a fundamental frequency or monic of pipe A of 400 Hz. The third harmonic of organ harmonic of pipe A. Find the lengths of pipe B, with one end open, has the same frequency as the secon the two pipes A and B. Speed of sound in air is 340 m/s one end open ds open, has a fundamental frequency (2 Pipe A, which inl oo lates at to second lowet ha 2.) Pipe A, which is 1.2 m long and open at both ends, oscillates at its third lowest frequ 8 and open at both ends, oscillates at its third lowest frequency. Pipe B which is d B closed at one end, oscillates at its second lowest harmonic frequency. The frequencies of pipes happen to match. Find the length of the pipe B, of the pipe B, ine A (measured f (a) the location of nodes in pipe A (measured from one end), and (b) (c) the lowest harmonic frequency of pipe A. A tube 1.2m long is closed at one end. A stretched wire is placed near the open end. The wire is 0.330m long and has a mass of 9.60g. It is fixed at both ends and oscillates in its fundamental mode. By resonance, it sets the air column in the tube to oscillate at its fundamental frequency. Find 3. (a) the frequency, and (b) the tension of the wire.
