Diamond has a Debye temperature of Dt = 2000 K and a density of 3500 kg/m3.
The distance between nearest neighbors is 0.15 nm. Determine the velocity of
sound using the Debye approximation.

I have no idea where to even start with this question. Most books dont even mention the Debye approx. and all the others have very little or are so confusing!
