Photon and Phonon frequencies in the ZettaHz (10^21 Hz) and YottaHz (10^24 Hz) and
wavelengths down to Attometers (10^-18 meters) when looking at the frequency/wavelength
of gamma rays, quarks, and electrons.
Einstein (and others) throw in the atomic vibration frequency and energy in determining the specific
heat of matter.
Diamond at 331 K has an "Einstein Temperature" of 1300 K (which corresponds to
an infrared w3avelength of 11 microns)etc.
The Brillouin Effect allows Phonons (Sound Energy Quanta) to Beat/Heterdyne against
Photons (Light Energy Quanta) with the result that intermediate frequencies equal to the sum or difference
can be generated, and conversely, Photons can beat against Phonons with the same Beat/Heterdyne effect
(as originally proven by Garmire & Townes in 1964).
Does this imply a Hot Phonon Gas in H2O or D2O that doesn't necessarily show
up as a higher temperature?
