The first overtone of an open organ pipe beats with the first overtone of a closed organ pipe with a *** frequency of 2.2 Hz. The fundamental frequency of the closed organ pipe is 110 Hz . Find the lengths of the pipes. (speed of sound is 330m/)
Frequency of the first overtone for a open pipe is
f0 = 3 v/4l0
Frequency of the first overtone of a closed pipe is fc = 2v/2lc
Fundamental frequency of the closed pipe
