Nettet23. aug. 2011 · So I think the answer is yes. Aug 11, 2024 at 14:59. QED predicts that a photon can split into two photons of lower energy, in a strong magnetic field. This is believed to happen in the magnetospheres of the … NettetShort answer: a photon is a particle of light. Longer answer: light is energy. Sometimes we think of light as being a wave in the form of an electro-magnetic wave but other times it can be described as a particle. A photon in this case, is 1 unit of light with a variable amount of energy which depends on its frequency.
