Default what happens to reflected energy ?

Hi Miguel,

Power? Energy? One second? Choose one to talk about, and perhaps
the mystery of numbers might clear up.

one quanta an two quanta


Quanta? Two Quanta? We are now up to four intermixed terms.
Simplify. Choose one thing.

of 80 m radiation is 2.3 * 10^ -27 J, that
difference (my physic book say) it is unmeasurable experimentally
(this energy leap (skip?, hop?) it is in the order of 10^-8 smaller
that green light leap


True, but immaterial. You are confusing wavelength and quanta (no
surprise given the blearing of topic). Compare Green and IR. Is
there a correlation on a scale of two that predicts out to a scale of
10^8? Compare Green and deep IR. Is there a correlation on a scale
of ten that predicts out to a scale of 10^8? Compare Green and the
Sub-millimeter band. Is there a correlation on a scale of 100 that
predicts out to a scale of 10^8?

(in reality my book -Resnick Halliday- give a
moving dust particle example with quantic number very much lower than
my 80 m example yet = n = 3 * 10^14, they said "we can not
distiguish energy difference among n = 3 * 10^14 and n = [3 * 10^14]
+1")


So a quantum of smaller energy of a dust particle is measureable but
80M transmission is not? Common sense is wheezing in this dust.

OK, so they are talking about the difference in quantum, not energy.
Would it surprise you that you cannot even tell the difference between
one quanta of green light and two with conventional detecting
technology?

What it is the ohysical sense of working with magnitudes we can not
measure? Nobody (as we know) use (or need) quantum mechanics to deal
with (or explain) locomotive movement :)


The limitation is called Quatum Efficiency and the human eye is vastly
superior (to all but $1,000,000 components) at rougly QE = 50%.

Yes, yes, I know some people bring very strange ideas into the forums,


Indeed.
