Описание: It does not itself carry a charge. Light does not have a charge. "Charge" is just what we call the tendency of something to affect and be affected by electromagnetic fields, which are what light is made of. The reason positive and negative charges are attracted to each other is that they both give off these fields.Charges (electrons, positrons, nuclei) are accompanied by (''emit'') an electromagnetic field - a soft virtual photon cloud in terms of QED. Photons are elementary excitations of the quantum electromagnetic field. They do not carry charge.No, photons can never have a charge. This is because charge cannot exist without rest mass. ... Light has no electric chargeLight is PRODUCED BY a vibrating electric charge.Electrons have a negative charge, which means only that they move away from other negatively charged matter (other electrons) and are drawn to positively charged matter (protons, often ones in the nuclei of atoms). But photons are units (packets of energy) of an electromagnetic wave. They are not bits of matter.
