## Homework Statement

The fundamental frequency of an open organ pipe corresponds to the note middle C (f = 261.6 Hz on the chromatic musical scale). The third harmonic (f3) of another organ pipe that is closed at one end has the same frequency. Compare the lengths of these two pipes.

## Homework Equations

frequency = harmonic number x (speed of sound in the pipe)/(2)(length of the vibrating air column)

frequency = harmonic number x (speed of sound in the pipe)/(4)(length of the vibrating air column)
