Suppose that the range of output frequencies is from 75.3 Hz to18.0 kHz for a pipe organ. Take 343 m/s for the speed of sound. (a) What is the length (in terms of m) of the longest pipe open at both ends and producing sound at its fundamental frequency? (b) What is the length (interms of m) of the shortest pipe open at both ends and producing sound at its fundamental frequency?
