If the electron's in the ground state, it could absorb a four eV photon, or a six eV photon, or a seven eV photon. If the electron's at the second energy level, also called the first excited state, the electron could absorb a two eV photon or a three eV photon.

WebNow, to answer this question, we need to know what a photon actually fundamentally is. You may already be aware of the fact that light consists of electromagnetic waves.. This wave nature of light, however, is unable to explain some phenomena, such as the photoelectric effect, where a light beam can actually scatter off electrons from a piece of metal. WebTo explain the photoelectric effect, 19th-century physicists theorized that the oscillating electric field of the incoming light wave was heating the electrons and causing them to vibrate, eventually freeing them from the metal surface. This hypothesis was based on the assumption that light traveled purely as a wave through space. hout bay vet https://mariancare.org
