37.An organ pipe P1 closed at one end vibrating in its first overtone and another pipe P2open at both ends vibrating in third overtone are in resonance with a given tuning fork. The ratio of the length P1to that of P2is --------
First overtone of Closed organ pipe P1:
It is equal to 3rd harmonic.
Third overtone of open organ pipe P2:
It is equal to 4th harmonic.
Equate f1 and f2 to find the ratio of lengths: (condition of resonance)
It is equal to 3rd harmonic.
Third overtone of open organ pipe P2:
It is equal to 4th harmonic.
Equate f1 and f2 to find the ratio of lengths: (condition of resonance)
