WebApr 6, 2024 · The optical phonon, however has a different dispersion relation, where ω → (non-zero constant) as k → 0. In an optical phonon, neighbouring atoms move in opposite … Photon 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. Photon energy can be expressed using any unit of energy. Among the units commonly used to de…
