A drainage pipe running under a freeway is 33.0 m long. Both ends of the pipe are open, and wind blowing across one end causes the air inside to vibrate.
If the speed of sound on a particular day is 340 m/s , what will be the fundamental frequency of air vibration in this pipe?
What is the frequency of the lowest harmonic that would be audible to the human ear? (The lowest frequency we can hear is about 20 Hz.)
What will happen to the frequency in the later afternoon as the air begins to cool?

Pipe A, which is 2.40 m long and open at both ends, oscillates at its third lowest harmonic frequency. It is filled with air for which the speed of sound is 343 m/s. Pipe B, which is closed at one end, oscillates at its second lowest harmonic frequency. This frequency of B happens to match the frequency of A. An x axis extends along the interior of B, with x = O at the closed end. (a) How many nodes...

An organ pipe open at both ends has a length of 0.80 meters. The velocity of sound is 340 meter/second at a certain temperature T1. For these conditions, one has the lowest resonant frequency F1 for the pipe at the temperature T1. The length is held constant, and the temperature of the air increases to temperature T2. The new lowest resonant frequency F2 (at the higher temperature) will be a.) higher than the original lowest resonant frequency (F2>F1) b.) equal...
