    A pipe that is closed at one end is 0.5 meters long at 25o C.

    Sketch the standing wave pattern (loops with nodes and antinodes) for these
    three cases: (attached picture file)

    What is the wavelength of the 2nd overtone?
    If the air in the pipe is also at 25o C, what is the frequency of the 2nd overtone?

    For 2nd overtone:
    L = 0.5 meter = (0.5 + 0.5 + 0.25)*lembda = ...

    Solution Summary

    The wavelength of the 2nd overtone is found. A sketch of the standing wave pattern for three cases is included.
