WebMar 23, 2016 · The photon provides the energy to separate the pre-existing charges within the neutral Hydrogen atom. Another example would be the photoelectric effect (mentioned in previous posts). A photon striking the neutral cathode can eject a negative electron, leaving the cathode with an overall positive charge. WebNov 22, 2024 · Later on, those negative energy states were identified with an “equal-and-opposite” set of quanta that were shown to exist: antimatter counterparts to the known particles. It was a great leap forward to have a relativistic equation that described the earliest known fundamental particles, such as the electron, positron, muon, and more.
