Homework Help: Waves in a water xylophone

  1. Mar 5, 2013 #1
    1. How do you find the wavelength in a glass bottle water xylophone?

    2. How do you find the frequency?

    3. Where are the antinodes and nodes located?

    4. Where is the standing wave located?

    You should provide more details on the problem (for example how the bottle is modeled, if the walls are perfectly reflecting and so on)... and you should show also at least the reasoning you did and where you got stuck... we are here to help you understand how to do your homework, not to do it ourselves. Meaning that we need to see that you at least tried.

    Said this, with the information I have I can tell you that probably you have to impose perfect reflections at the boundaries. Therefore in practice you write the equation of the wave and you impose that at the ends it is null. It is much equal to what you do for a vibrating string. Then with that you can find the wavelength of the modes and their nodes and the maxima it has, and also the frequency once you have the wavelength (use the dispersion relation for that).
