<<Modern view

It has been shown that it is not necessary for light
to be "quantized" to explain the photoelectric effect[8].
The most common method employed by physicists to
calculate the probability of an atom ejecting an
electron relies on "Fermi's golden rule". Although based
upon quantum mechanics, the method treats the incident
light as an electromagnetic wave that causes an atom
and its constituent electrons to transition from one
energy state ("eigenstate") to another.

While one can use the classical electromagnetic
theory of light to describe the effect, one may also
use the modern quantum theory of light to describe
the photoelectric effect. However, the modern quantum
theory of light is not a "particle model", as it does
not always predict results which one would expect from
a naïve "particle" interpretation. An example would be
in the dependence on polarization with regard to the
direction electrons are emitted, a phenomenon that has
been considered useful in gathering polarization data
from black holes and neutron stars.[9]. >>

<<The Nobel Committee avoids committing itself to
the particle concept. Light-quanta or with modern
terminology, photons, were explicitly mentioned in
the reports on which the prize decision rested only
in connection with emission and absorption processes.
The Committee says that the most important application
of Einstein's photoelectric law and also its most
convincing confirmation has come from the use Bohr
made of it in his theory of atoms, which explains a
vast amount of spectroscopic data.>>

Frozen What!

Frozen sherbet is better.

The light propagation is independent of emitter and
absorber's motion.

None frozen.


<< where epsilon_0 and mu_0 are physical constants which
can be evaluated by performing two simple experiments
which involve measuring the force of attraction between
two fixed charges and two fixed parallel current carrying
wires. According to the relativity principle, these experiments
must yield the same values for epsilon_0 and mu_0 in all
inertial frames. Thus, the speed of light must be the
same in all inertial frames. >>
