Question
A cylindrical column of air that in closed at one end has an initial length of 1.38. A disturbance across the open end produces a standing wave within the air column
which resonates with the 1st harmonic. If the length of the column begin to decrease at a rate of 0.052 m/s, at what time is the fundamental frequency 128 Hz?
