A pipe organ may contain tens of thousands of pipes of varying
shapes, sizes and materials.
(a) A pipe destined for an organ is open at both ends and has a
length of 1.2 m. What is the wavelength of the longest standing
wave that can be produced by this pipe?
(b) The fundamental frequency produced by the pipe is measured to
be 150 Hz. Calculate the speed of sound for the air in the
pipe.
(c) If one end of this pipe is closed, as shown below, the allowed
standing waves change. Indicate in the figure below the locations
of the nodes (N) and antinodes (AN) of the fundamental standing
wave inside the pipe.
(d) Calculate the fundamental frequency produced by the pipe closed
at one end.
