(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

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.

2. Relevant 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)

3. The attempt at a solution

I'm not sure where to go from here
