By the way, I am having second thoughts as to whether or not there
should be a 2*pi factor in there, since most physics formulas deal
with frequency in radians per second, not cycles per second. But the
photon energy formulas usually deal with wavelength, and I have never
seen one that assumes a wavelength is a radian of a cycle, rather that
a full cycle, so, perhaps Hz is the correct unit.

If anyone can clear this up for me, I would appreciate it.

Hi John,

That would be 2 pi radians per second as frequency - same thing as a
cycle. For photonic interactions the classic treatment is usually
with wavenumber as frequency not cycles nor radians. However, the 2
pi difference is the difference between the Planck constant
represented as h, and its rational equivalent (with 2 pi divided out)
of h-bar.
