Make sure you can write down the potential energy, derive the equation of motion and dispersion relaton, and understand the long wavelength limit.

Un(t)=e^(i(kna-wt)

wk=2wd(sin(ka/2))

long lambda limit means wk-->0, no restoring force for uniform translation of all atoms.

g(e) for electrons in 1D, 2D, 3D
