WebAug 15, 2024 · 18. The equation E=nhv is used to find the energy of the photon. Energy can also be released or absorbed in small discrete packages that mean energy is quantized. Each package is termed ”quantum”. Einstein expanded on this theory with Planck’s to show that radiant energy is also quantized and the quantum of radiant energy is called a photon. Webgamma ray, electromagnetic radiation of the shortest wavelength and highest energy. Gamma rays are produced in the disintegration of radioactive atomic nuclei and in the decay of certain subatomic particles. The commonly accepted definitions of the gamma-ray and X-ray regions of the electromagnetic spectrum include some wavelength overlap, with … 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 … See more An FM radio station transmitting at 100 MHz emits photons with an energy of about 4.1357 × 10 eV.
