Homework Help: Closed Cylinder Resonance

    Is there a theoretical limit to the lowest note achievable in a closed tube(Pop bottle)?

    Heres the question in context:
    I've got what I believe to be the correct:

    I've searched all over for something but cant find anything. From what I can reason there would be a limit for two reasons:
    1) Because the human ear can only hear a limited about of frequencies.(I assume this is correct but doesn't really relate to the given situation)
    2) Frequency and wavelength are inversely proportional so eventually at a low enough frequency the wavelength will be so great that 1/4 of its wavelength is greater than the length of the tube.
