why photon has no charge though it is produced by either proton and electron, which are both charged??
Danger said:As far as I understand particle physics, a photon is a bosun. As such, it transfers a charge from one place to another, but doesn't have one of its own.
Danger said:Okay, I knew that a photon can be emitted by an electron reverting to ground state, but I didn't realize that it could take the negative charge with it when it left.
