Si unit of radiant power
Webb22 maj 2024 · In physics, radiant energy is the energy of electromagnetic and gravitational radiation. The term “ radiant energy ” is most commonly used in the fields of radiometry, solar energy, heating and lighting. As energy, its SI unit is the joule (J). The quantity of radiant energy may be calculated by integrating radiant flux with respect to time.
