Mode vs node

  1. Jun 1, 2007 #1
    1. The problem statement, all variables and given/known data
    What is the difference between a mode and a node

    3. The attempt at a solution
    I am not really sure, because they seem exactly the same to me. Any help would be much appreciated!

    In a standing wave, a node is a place where the medium doesn't move--as opposed to an anti-node, which has maximum movement. See this: Nodes and anti-nodes

    The vibration mode has to do with the frequency (or wavelength) of the standing wave, which can be determined by counting the number of nodes in the standing wave. Read this about Harmonics, each harmonic being another vibrational mode.
