It's usually considered that the lower energy photons
make heat, and the higher energy photons make
ionizing radiation, in accords with how they're not
reflected instead absorbed and perhaps transmitted.

Then, particularly organized systems like the photoreceptors
of plant cells or the CCD's, have carefully contrived means
to arrive at a usual sort of photosynthetically active radiation
or the green/gray luminance and the red/blue chrominance
channels, of usual sorts electronic imaging devices.


Yeah, though, it sort of boggles people that heat
can be transmitted as via optical radiation when
the vacuum of space is not much of a thermal
insulator.


Then of course there's a very great sort of establishment
of the opto-electronic effect, for various what are
called "junctions", when the energy within a photon,
at a junction, makes an exchange, a transition of the
_form_ of its energy, to an electron in electron physics,
then that the frequency and wavelength of an electron
are according to light's photons, while, the energy of
the photons, are according to the e/m ratio of electron
physics, in the world of atomic physics.


That is to say, the intensity of the surface of the illumination
according to intensity and the coherence of the light,
is related thusly to the current across a surface or according
moreso to a condenser, helping explain why these atomically
fine quantities are exactly related to gross bulk aggregates.



Then there's a whole zoo of virtual photons that are
really "non-chalant-ons" or "ag-nost-ions", yet those
are mostly only so that QED doesn't feel bad being
not a particle theory.


The optical light's photons are "rays", though, and
the nuclear radiation besides what immediately
ionizes, is also "rays".

(The, "beams", are mostly reserved for more contrived
particular organizations of collimated rays.)


Yeah, the particle/wave way of wavelength,
is sort of light's.

Then it's like, "electron, you're photonic radiation".
