3. Atomic vibrations in a metal. Consider point ions of mass M and charge e immersed
in a uniform sea of conduction electrons. The ions are imagined to be in stable
equilibrium when at regular lattice points. If one ion is displaced a small distance r
from its equilibrium position, the restoring force is largely due to the electric charge
within the sphere of radius r centered at the equilibrium position. Take the number
density of ions (or of conduction electrons ) as 3/(47R³), which defines R. (a) Show
that the frequency of a single ion set into oscillation is @= (e²/MR³) ¹/2. (b)
Estimate the value of this frequency for sodium, roughly. (c) From (a), (b), and some
common sense, estimate the order of magnitude of the velocity of sound in metal.
