I Normal Modes Question

  1. Mar 26, 2016 #1
    If I have a system where the following is found to describe the motion of three particles:

    The normal modes of the system are given by the following eigenvectors: $$(1,0,-1), (1,1,1), (1,-2,1)$$
    How can I find the corresponding eigenfrequencies? It should be simple... What am I missing?

    Is this for schoolwork?

    This is something I found in a pdf online where it simply asserted what the eigenfrequencies were... and not how to find them.
