Had a sound system in a car... going down the road at 60 MPH (had a 100 A
alternator - biggest battery that would fit)... turn the radio up and up and
Till it would shut down the computer and kill the engine. :-)
Infrared is electromagnetic radiation at frequencies just below the
visible spectrum (next to red). That is NOT heat. The fact that EM is
constantly being converted to and from heat in no way makes them the
There is (still) no such thing as "infrared heat". Infrared radiation
is produced by warm objects. Heating these objects further produces
more visible light (as seen in flames and heating elements, and in
Photographic film, as well as CCD arrays in digital cameras, is
sensitive to electromagnetic radiation in the infrared range.
It isn't just warm things that radiate photons, it is
everything, except all things also absorb photons,
depending on temperature differences and other
But I am curious about what the special thing
that CO2 is supposed to have, it is a molecule with
atoms vibrating or moving in some way, but those
movements are not involved in the sensible heat
measured, only the velocity of the entire molecule
relative to neighbor molecules can transfer "heat".
"Heat" is not a thing in itself, it is only the
motion of the molecules and how fast and how
hard they hit when they bounce off other molecules.
Of course monatomic atoms are considered
to be "molecules" in some ways.
I understand "Black Chrome" coatings on
copper sheet or foil will absorb solar energy very
well and not emit in short wavelengths, but chances
are that anything that emits long waves will also
absorb long waves, and CO2 has a very small
specific heat compared to water vapor, and
there must be a lot of difference in the latent
heat of vaporization between the two molecules.
Joe Fischer I drive the right lane.
