Re: Krypton filled Fibre Supercontinuum laser

RCB, I never thought which was larger, a photon or an electron, so I went searching, found this answer:

The electron is larger. Although it has a small mass, a photon has no mass. A photon is the smallest unit of energy that can exist. It is the carrier particle for the electromagnetic force.

Cyparagon, where are you?
