An open pipe is resonance is its 2^(nd) harmonic with tuning fork of freqency f_(1) . Now it is closed at one end. If the frequency of the tuning fork is increases slowly from f_(1) , then agaain a resonance is obtained with a_(1) frequency f_(2) . if in this case the pipe vibrates n^(th) harmonics, then
