👉 Light particles, or photons, originate from the fundamental processes of atomic and subatomic interactions. At their core, photons are quanta of electromagnetic radiation, meaning they carry discrete packets of energy and momentum. These particles emerge from the acceleration of charged particles, such as electrons, in various physical phenomena. For instance, when an electron transitions between energy levels within an atom or molecule, it can release energy in the form of a photon to return to a lower energy state. This process is central to the emission spectra observed in stars and other celestial bodies. Additionally, photons are produced during the ionization of atoms, where electrons are stripped away, and during high-energy events like cosmic ray interactions with the Earth's atmosphere. The concept of light particles as discrete entities was first proposed by Albert Einstein in his explanation of the photoelectric effect, solidifying their role as fundamental building blocks of electromagnetic radiation.
