Problem 3: An organ pipe is open on both ends. Suppose the pipe plays the note C1 (C 3 octaves below middle C), which has a frequency off = 32.7 Hz. The speed of sound in air is 330 m/s. How long is the pipe? To answer this question: (a) Draw a picture of the waveform of this fundamental (n = 1) frequency in the pipe. (b) Find the wavelength of the waveform according to (a) in terms of L. (c) Solve for L using an appropriate relationship between velocity, wavelength, and frequency
