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… WebAnswer (1 of 2): Well, just the one if the photon is carrying one Joule. Two if they carry half a Joule each. Typically you don’t generate energy, you generate power. A single 1-Joule photon arriving every second delivers 1W of power. Of course, it is unsual to get photon so energetic. The b...
