WebJul 22, 2009 · (The energy of a photon is E = hf, where E is the energy, h is Planck's constant, and f is the frequency of the photon.) Conversely, when an atom absorbs a … WebJul 3, 2015 · No, it is sufficient for the photon energy to exceed the band gap. Any excess energy is transformed into kinetic energy for the electron in the new band. You get exactly the same effect when ionizing an atom - the excess energy simply powers the electron into a faster continuum state.

WebSep 10, 2024 · The electron will as you say move to a higher energy level, and the photon in this case does not cease to exist at all. It just transfers part of its energy to the electron, and you are correct, the photon's wavelength changes, increases. absorption; In this case, the photon transfers all its energy to the electron/atom system, and the photon ... WebSep 3, 2024 · The electron does not absorb a photon. (I am ignoring the issue of "soft photons" mentioned in one of the answers linked by the OP, which in my opinion not related to the question the OP is asking). A Hydrogen atom consisting of an electron orbiting a proton can absorb a photon. This will happen if the photon's energy is close to one of a ... WebIf you mean to ask, "why can't an electron absorb part of a photon's energy", the answer is that the electrons can absorb part of a photon's energy. This is called Compton scattering. Here, a photon is scattered … iscas epapers.org
