Consider two pipes labelled A and B. Pipe A is open at both ends
and has length πΏπ΄=0.340πLA=0.340m. Pipe B is closed at
one end and open at the other end and has
length πΏπ΅=12πΏπ΄LB=12LA. Pipe B has standing waves set up
in it. We can use the standing waves in Pipe B to excite standing
waves in Pipe A. Which of the harmonics in Pipe B can excite a
harmonic in Pipe A?
Hint: The speed of sound in air
is 340ππ β1
