Question: Organ pipe A, with both ends open, has a fundamental frequency of 350 Hz. The third harmonic of organ pipe B, with one end

Organ pipe A, with both ends open, has a fundamental frequency of 350 Hz. The third harmonic of organ pipe B, with one end open, has the same frequency as the second harmonic of pipe A. How long are (a) pipe A and (b) pipe B? (Take the speed of sound to be 343 m/s.) (a) Number Mi Units (b) Number Units A tuning fork of unknown frequency makes 6 beats per second with a standard fork of frequency 449 Hz. The beat frequency decreases when a small piece of wax is put on a prong of the first fork. What is the frequency of this fork? Number Units
