When the electron transits from an excited state to its decrease electricity state, it will gice off the equal amound of power needed to increase to that level. This emitted electricity is a photon.
A photon is a tiny particle that involves waves of electromagnetic radiation. As shown through Maxwell, photons are just electric fields touring via space. Photons have no charge, no resting mass, and journey at the velocity of light.
Chemical reactions inside your body, without releasing strength and producing heat, are additionally emitting small numbers of photons, fundamental particles of light. The glow is strongest in the late afternoon, and round the lower part of your face.
