Photon gamma def
WebPair production is the creation of a subatomic particle and its antiparticle from a neutral boson.Examples include creating an electron and a positron, a muon and an antimuon, or a proton and an antiproton.Pair production often refers specifically to a photon creating an electron–positron pair near a nucleus. As energy must be conserved, for pair production … WebThis video introduces and explains the Photon for A Level Physics.What exactly is a photon?
