Use the worked example above to help you solve this problem. A pipe is 2.38 m long.
(a) Determine the frequencies of the first three harmonics if the pipe is open at both ends. Take 349 m/s as the speed of sound in air.
(b) How many harmonic frequencies of this pipe lie in the audible range, from 20 Hz to 20000 Hz?
(c) What are the three lowest possible frequencies if the pipe is closed at on end and open at the other?
