The fundamental tone produced by an organ pipe has a frequency of 110 Hz. Some other frequencies in the notes produced by this pipe are 220, 440, 550, 660 Hz. Is this pipe open at both ends or open at one end and closed at the other? Calculate the effective length of the pipe. (Speed of sound =330 ms-1.)
