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 Plank's constant and has the numerical value of 6.626*10^-34 J*s or 4.135*10^-15 eV*s.
