Def from Websters: LIGHT - as per 'radiation';
"An Electromagnetic radiation in the wavelength range including infared
visible, unltraviolet, and X-rays and traveling in a vacuum with the speed
of about 186,281 miles per sec. specifically: the part of this range that
is visable to the human eye"

Some background.... in 1905 Einstein generalized Plank's results (assumed
that that oscillator could change energy bu losing or gaining energy per
quanta or magnitude 'hv') to pstulate that when an oscillator loses
quantum energy hv, the oscillator emits a pulse of light having an energy
hv, and that the frequency of the light emitted is equal to the same 'v'.
In Einsteins view... light consists of energy pulses called quanta, or
photons,
and the quanity of energy carried by the photon is 'hv' = 'hc/lamba'!
where the lamba is the wavelength of the light (photon - quanta).

Hope that helps some...I think we are speaking of the same thing as Einstein
had known and stated.
