Rod connecting positive and negative mass. 6. th. Interstellar Symposium, Wichita, Kansas 2024. 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 d…

WebMay 24, 2024 · 4. Why can a neutral pion decay into 2 photons but not one? It is due to the law of conservation of energy and momentum. A particle with a given mass cannot "decay" to only one smaller mass particle because the decay to one particle at the center of mass would not conserve energy, unless it was in motion, which would not conserve momentum.
