WebPhoton 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. WebThe dual-wavelength radiation thermometer calculates the temperature T from the ratio R of the radiant light intensity at two wavelengths, that is, the radiant light intensity E λ1 at the wavelength λ 1 and the radiant light intensity E λ2 at the wavelength λ 2. The ratio R is represented by the following formula (5).
