Natural Frequencies of oscillation

  1. Nov 4, 2012 #1
    1. The problem statement, all variables and given/known data

    What are the natural frequencies (not wavelengths) of oscillation formed in a pipe that is open at both ends and a pipe open at one end and closed at the other?

    2. Relevant equations



    3. The attempt at a solution

    I don't understand this. I keep reading something about 2L and 4L.

    You have standing waves in the pipes and the wavelength of the waves are determined by the length of the pipes. How?

    You also know the relation between frequency, speed of sound and wavelength.

    Presumably you can find the wavelengths of the modes?
    What is the relationship between wavelength and frequency?

    Antinodes and nodes?

    What is that supposed to mean? Can you offer up a complete thought?

    ... are you telling me that you do not know the relationship between wavelength and frequency? It's in your course notes.

    If you mean something else then please try again.
    Generally the more you can say about how you are thinking about the problem (in relation to the feedback you have so far) the more we can do to help you. The less you say - the less we can do. Don't worry about looking silly - we've all been there.
