Sentences with phrase «em spectrum»
Ordinary atoms, once ionized by the removal of one or more electrons, also emit a continuum EM spectrum, which is not quantized, because a newly captured free electron can have any initial energy before being captured by the ion.

At some point in the near future, solar panels will absorb the whole EM spectrum.
Is it a gas that absorbs and emit IR within certain bands of the EM spectrum?
KS4 Physics EM SPectrum TV show resources https://www.tes.co.uk/teaching-resource/The-EM-Spectrum-TV-Show-6125027/;
However, very little of the rest of the EM spectrum can penetrate the thick layers of our atmosphere (Figure 2).

Join the GSAM workshop to explore EM through a multi-asset lens; looking at investment techniques for allocating across the spectrum of EM asset classes, as well as sharing our views on the most attractive opportunities for generating capital growth and income.
Otherwise, EM still remains the most attractively valued of the equity spectrum.
o scientists have tricked the outgoing spectra of the earth into emitting less EM waves in the GHG wavelengths;
By the same token, in collisions even symmetrical molecules like N2 or O2 can exhibit an accelerating electric charge and therefore emit EM radiation in a continuum spectrum.
more carbon dioxide in the lower atmosphere means more little «point sources» for more absorbed EM in the infrared part of the spectrum, (infrared that re-radiated from the earth's surface after sunlight hit it and got absorbed); and since point sources radiate in a spherical pattern, that means more «back radiation» to earth, on balance... and this changes the «standing pattern» of energy flow in and out of the earth system, creating a time differential, so it starts to re-adjust...
It is a classical physics consequence of the accelerations of electric charge; which according to Maxwell's equations must (and do) result in the radiation of an EM wave (or photon if you wish; which has a continuous energy spectrum; not a quantized one.
Any other form of energy can be turned into heat, either partially, or completely; and what lay folks refer to as «heat» is simply the result of turning some other form of energy; which can include EM radiation; once again, all the way from down to but not including DC, up to the end of the gama ray spectrum (orbeyond), into the waste mechanical energy of some physical matter; and for most people that is a result of absorption of EM radiation by mostly water in the human body; that's what WE feel as «heat».
In particular «Thermal» EM radiation is not Atomic Line spectra, nor is it Molecular Band spectra, (which Phil has painstakingly pointed out that N2 Na O2 are largely inactive on; both theoretically, and experimentally).
