WebDec 17, 2024 · Here the mode decomposition is not unique. We can decompose the EM field into plane waves (infinite radius) or Hmite Gaussian beams (well defined radius but varies along the z-coordinate) or other mode families (e.g. spherical vector multipole solutions). So in this case I would say we can not assign a unique radius to a photon.

WebA proton has a radius. It's about 0.87 fm (femtometers = 10-15 meters). This is defined roughly as the physical space in which the charge of the proton resides. It's obtained via election scattering experiments. Muon scattering experiments give a smaller radius at around 0.84 fm. This discrepancy is an unsolved problem in physics. WebIch habe gelesen, dass das Photon keine Masse hat, aber mein Lehrer sagt, dass das Photon Masse hat, weil die Sonne es anziehen kann (wie in den Experimenten zum Beweis der Relativitätstheorie).
