Question

what are photons?are they same as protons?​

Answer 1

Proton: a particle with well-defined rest mass and well-defined charge. At rest, all protons are identical. Bound to other protons and to neutrons by strong nuclear force to form atomic nuclei.

Photon: a particle with no rest mass, incapable of rest, always travels at speed of light; carries an amount of energy defined by its frequency (or rather, a frequency defined by its energy). A quantum of light, or the particle exchanged in electromagnetic force interaction.
