You are studying standing sound waves in an organ pipe of length L with both ends open

a) What wavelength of sound can exist as standing waves in this pipe? Express your answer in terms of the length L.

b) Assume that the length of the organ pipe is L=24cm. You have excited a standing sound wave in the tube, and you observe that it has displacement nodes at 4cm, 12cm and 20 cm measured from one end of the pipe. In which harmonic, n, is the air in the pipe oscillating?

c) What is the frequency of the musical tone produced by the organ pipe in the situation described in part b?
