==Key Stage 5==
===Meaning===
'''Photons''' ('''γ''') are [[boson]]s responsible for mediating the [[Electromagnetic Interaction|electromagnetic interaction]] and are the [[Subatomic Particle|particle]] associated with [[Electromagnetic Wave|electromagnetic waves]].

===About Photons===
: The '''photon''' is denoted with the lower case Greek letter γ (gamma).
: '''Photons''' have no [[mass]] and therefore can mediate the [[Electromagnetic Interaction|electromagnetic interaction]] over an infinite range.
: '''Photons''' carry [[momentum]] without carrying [[mass]] and are therefore able to change the direction of motion of other [[Subatomic Particle|subatomic particles]].
: '''Photons''' do not carry [[Electrical Charge|charge]], but allow [[Subatomic Particle|particles]] with [[Electrical Charge|charge]] to exchange [[momentum]].
