Hi Guys,(adsbygoogle = window.adsbygoogle || []).push({});

I am learning some solid state physics.

I see a lot of pictures with Phonon Dispersion Relation, with

[itex]\omega (\vec{k})[/itex] on the y-axis and [itex]\Gamma, X, M, \Gamma, R[/itex] on the x-axis.

I don't understand, why the angular frequenzy [itex]\omega (\vec{k})[/itex] is important.

Or why is this information important?

THX
