A Photon is a quantised packet of electromagnetic radiation <ref>A French, P Taylor.(1978). A Introduction to Quantum Physics. MIT: CRC Press.</ref>. It is the elementary exchange particle for the electromagnetic force. The Energy of a photon (in Joules) depends on its frequency and is given by the equation:
'''E = hf'''
where '''f''' is the frequency of the electromagnetic wave and h = 6.626*10^-34 (Planks constant).
