Photon Energy


The following calculator calculates the energy of photon which is inversly propotional to wavelength.



A photon is defined as the quantum of electromagnetic radiation. The term quantum refers to the smallest elemental unit of a quantity. Hence, one quantum of electromagnetic energy is known as a photon. Value of planks constant h=6.26*10-34 Js.
