I know that accelerating electrons in a solid are responsible for the emission, absorption and reflection of light.
However, what role do the lattice vibrations play? These oscillating atoms are charge distributions and should emit radiation too, right?
As far as I can remember, the maximum lattice vibration frequency (Debye frequency) is in the infrared range typically. Does this mean that the lattice DOES emit radiation, but it is of such low frequency and intensity that it is negligible?
