A particular tube for a pipe organ is 4m long and open at both ends. The speed of sound is about 340m/s. Draw the first three harmonics and find the frequencies for the pressure wave view of sound. For each frequency, find another tube length that could also have this frequency as a harmonic. Now pretend the tube is closed at one end. Draw the first two harmonics and find the frequencies.
