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.

The vocal cords, two lipshaped memrane folds in the upper
trachea as indicated in the figure, are responsible for vocal sound
production. The voices of males and females often have different
sonic characteristics: Male vocals have an average fundamental
frequency of about 140 Hz, while female vocals have an average of
about 230 Hz.
