I am trying to find a succinct definition of normal coordinates and normal modes - relating to numerous coupled harmonic oscillators.
What exactly do the normal coordinates describe about these coupled harmonic oscillators?
I know that for normal modes, all parts of the system move with the same frequency. However I was told to find a definition relating the concept of normal modes explicitly to harmonic oscillators. (This is in relation to phonons - where a phonon is described as an excitation of a normal mode).
Thanks
