Photon explained
WebABSTRACT. The idea of the photon has stirred the imaginations of physicists ever since 1905 when Einstein originally proposed the use of light quanta to explain the photoelectric … WebWhat is the mass of a photon? Does the photon have mass? After all, it has energy and energy is equivalent to mass. Photons are traditionally said to be massless. This is a figure of speech that physicists use to describe something about how a photon’s particle-like properties are described by the language of special relativity.

Instead … WebEinstein showed that these results can be explained by two assumptions: (1) that light is composed of corpuscles or photons, the energy of which is given by Planck’s relationship, and (2) that an atom in the metal can absorb either a whole photon or nothing. Part of the energy of the absorbed photon frees an electron, which requires a fixed ...
WebOct 7, 2024 · Figure 7.3.6: Absorption and Emission Spectra. Absorption of light by a hydrogen atom. (a) When a hydrogen atom absorbs a photon of light, an electron is excited to an orbit that has a higher energy and larger value of n. (b) Images of the emission and absorption spectra of hydrogen are shown here. WebSo, in fact, the quantum field theoretical explanation for why a photon does not have mass is that gauge symmetry forbids it. Therefore, if we want quantum electrodynamics to work like it should and also agree with experiments, the photon cannot have a mass (this is quite an important point as all experimental evidence also suggests the photon ...
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 … 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.
WebEinstein recognized that this could be explained by Plank's equation where one could define a "particle of light" or photon as having a fundamental energy of \[E_{photon} = h\nu\] in an electric field, it can kick an electron off the object and a current can flow. Einstein was able to use Plank's quantizations hypothesis to explain the ...

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. small plastic tubingA photon (from Ancient Greek φῶς, φωτός (phôs, phōtós) 'light') is an elementary particle that is a quantum of the electromagnetic field, including electromagnetic radiation such as light and radio waves, and the force carrier for the electromagnetic force.
