Lowest angular frequncy

  1. Jun 21, 2012 #1
    My question is; why for a system oscillating in a normal mode does the lowest angular frequency relate to the particles in that system oscillating in phase. I understand that the signs of the corresponding vector are the same,but what relation is it to the lowest angular frequency.

    Thanks for any suggestions

    Please refer to Einstein modes. Normal mode can have any frequency (not only lowest one).

    But the question ask: why for in-phase motion is the associated angular frequency the lowest, intermediate or highest (obviously there are 3 normal modes). The answer is the lowest angular frequency, but the question then asks; is this to be expected? ie why is the lowest angular frequency associated with in phase motion
