When a photon that has at least double the energy that is needed to move an electron strikes the lead selenide quantum dots, it can excite two or more electrons instead of letting the extra energy go to waste, generating more current than a conventional solar cell.

When a photon collides with an object such as a light sail, it transfers some of that momentum to the object.

When the photon travels through a gravitational field, its frequency and therefore its energy will change due to the gravitational redshift.

When a photon is absorbed through any such transition, the molecule is then in an excited state, Depending on the specific energy levels, the molecule may partly or wholly de-excite by emission of photons of longer wavelength (to be absorbed in turn by other molecules).

When that photon hits an atom, that energy can be absorbed.

So Gavin, you are claiming that in the GHE when a photon comes in it sits around in the air until man releases CO2 which results in warming which results in more water vapor which THEN absorbs the energy photon to create feedback?

When a photon hits a molecule, if it has too much energy, enough is absorbed to boost an electron to the next higher orbit and the rest is immediately radiated away.

Not exact matches

Coding information into photons is easy enough — we already do that when we send information via optical fiber.

those stars you see, the light takes hundreds of thousands of years to reach us, and when you see that light from them, you are seeing what they looked like thousands of years ago when that group of photons was thrust out by that star / galaxy, which than takes several light years to reach us, which also means you are looking at the past, thousands and hundreds of thousand of years into the past!
