Diameter of a photon

WebThe size of a photon, Mr Bromilow, is whatever it is observed to be at the time a measurement is taken. It is not fixed and has no lower or upper bound. Peter Jones, … WebJan 11, 2024 · 169. 22. PeterDonis said: A photon isn't a little ball with a well-defined size, nor is it a point particle. The questions you are asking aren't even well-defined and don't have meaningful answers. The only real "size" that has meaning for a photon is its wavelength, and that is frame dependent.
