Question
An open organ pipe is closed suddenly with the result that the second overtone of the closed pipe is found to be higher in frequency by 100 than the first overtone of the original pipe. Then the fundamental frequency of the open pipe is
The correct answer is: 
Frequency of second overtone (fifth harmonic) of close pipe

Frequency of first overtone (second harmonic) of open pipe

Accordingly,

Or

Or

Fundamental frequency of open pipe
