Energy per photon of all electromagnetic spectrum classes
The amount of energy is directly related to the frequency and the electromagnetic wavelength of the photon. The higher the frequency of the photon, the greater its energy and the longer the photon wavelength, the less its energy. The next table presents the energy per photon for each class of electromagnetic radiation.
