It is interesting to see that Sam
does not know the difference between an electro-magnetic (LIght) pulse and
what some people refer to as a photon.
Apparently Sam thinks that if I click my flashlight (Or my laser or
transmitter.)
off and on five times,
he can count five photons.
He probably could, with an apparatus that measures electrons. :-)
[1] Light beam hits sensitized plate.
[2] Sensitized plate emits electrons.
[3] Electrons are pushed through something that counts them.
Granted, there are some issues here.
Sam's God Einstein wouldn't like to hear that, as his divinity preached
that the photoelectric effect was a function of frequencies, not pulses.
ONE electro-magnetic pulse can cause many electrons to change various
energy levels.
Depends on the strength of the pulse. A single photon has energy h*f, or
h*c/lambda.
Since h = 6.6260693 * 10^-34 J s, a 500 nm pulse would therefore have the
energy of about 3.973 * 10^-19 J, or 2.48 eV. A common flashlight would
generate quite a few of these.
I might point out to The Ghost
that the energy contained in a "500 nm pulse"
depends upon the frequency components of the pulse.
A "500 nm pulse" can be composed of many "h*f"'s,
and one doesn't know the energy, until one knows the "f"s.
I suggest that the Ghost and Sam
read some of the works out of the Max Planck Institute
as they are the experts in light pulses.
