WebScience. By the standard definitions of "x-ray" and "gamma ray", any photon produced by bremsstrahlung is by definition an x-ray and not a gamma ray. However, there's no upper bound to the photon energy that can be produced by bremsstrahlung. That's the neat part, gamma rays are just x-rays from nuclear interactions.

Web11 apr. 2024 · The advancement in this section of physics also revealed the presence of a heavier particle, a carrier of forces hidden from our eyes. This particle is called dark photon and can be connected to the presence of dark matter. They exhibit properties similar to photons but remain hidden. WebPhotons are the fundamental unit (quanta) of light. They have the unique property of being both particle and wave. They are often described as being "bundles of pure energy traveling at the speed of light". And one of the more interesting questions that physicists have raised is whether or not they have mass. They certainly have an energy given ...
