WebHowever, the atom has to lose energy to do this, and so it releases a photon of the same energy as the one it absorbed (albeit most likely into some other direction from which it was absorbed). This process is called emission because a photon of light is emitted by the atom, again at a very specific wavelength. WebApr 15, 2024 · At temperatures higher than a few hundred degrees, electrons will gain energy and move to a higher shell, but only momentarily. When the electrons drop back down to their natural shell, they emit light .This is why fires and other very hot objects seem to glow.Electrons are also primarily responsible for many of the chemical properties of atoms.

WebAssuming that a 60W "white" light bulb emits only yellow light, how many photons does it emit per second? Each of these photons carries some momentum. WebWhen an atom emits light, a photon is created, and the energy of the photon must equal the energy lost by the atom when an electron jumps from one orbit to another. A big jump for an electron requires a high energy photon, or short wavelength light. But like photons, they have both wave and particle properties.
