Photonic emission

WebPhoton energy is the energy carried by a single photon. The amount of energy is directly proportional to the photon's electromagnetic frequency and thus, equivalently, is inversely proportional to the wavelength. The higher the photon's frequency, the higher its energy. Equivalently, the longer the photon's wavelength, the lower its energy. WebPhotoelectric emission is also called as photoemission or photoelectron emission or photoelectric effect. In this method, light or photons is used to remove the free electrons …
