Photons
From Conservapedia
A Photon is a discrete packet of electromagnetic radiation [1]. It is the elementary exchange particle for the electromagnetic force. The Energy of a photon depends on its frequency and is given by the equation:
E = hf
where f is the frequency of the electromagnetic wave and h is Planck's constant and has the numerical value of 
Js (Joules times second) or 
eV s (electron volts times second).
