Photon explained
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 ...

WebAccording to the photon theory of light, photons: behave like a particle and a wave, simultaneously move at a constant velocity, c = 2.9979 x 10 8 m/s (i.e. "the speed of light"), in empty space have zero mass and rest energy carry energy and momentum, which are … Ionizing Versus Non-Ionizing Radiation . Electromagnetic radiation may be … 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.
WebEinstein was able to use Planck's quantization hypothesis to explain the photoelectric effect. As indicated in Figure 6.2.2 a minimum energy of 2.0 eV is required to eject a photon off of potassium, and so red light would not work, while green and purple would. Figure 6.2.2: Potassium requires 2.0eV to eject an electron, and a photon of red ...

A photon (being a packet of energy) carries a specific amount of energy. We can use the idea of energy to connect the photon and wave models. How much energy a photon has depends on its frequency ...
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 ...
