Photons: Definition & How Photons Measured & Calculated

WebHow many photons per second are emitted by the antenna of a microwave oven, if its power output is 1.00 kW at a frequency of 2560 MHz? ... So that's 1 times 10 to the 3 watts, which I could write instead as joules per second and then divide it by 6.626 times 10 to the minus 34 joule seconds. 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… granit big brotherWeb1 mole photons = 6.022 × 10 23 photons. Energy in joules per photon = 46.382 × 10 − 20 J.
