Stopped Organ Pipe
A 135 cm long organ pipe is stopped at one end and open at the other. Near the open end there is a loudspeaker that is driven with an audio oscillator whose frequency can be varied from 10.0 to 4,500 HZ.
1. Write an expression for the number of n dissimilar frequencies, up to the limit of the oscillator that can produce resonance in the organ pipe.
2. Write and expression for the highest frequency FN, up to the limit of the oscillator that can produce resonance in the organ pipe.
