Analysis Ĭherenkov radiation glowing in the core of a TRIGA reactor.īecause electromagnetic (EM) radiation can be conceptualized as a stream of photons, radiant energy can be viewed as photon energy – the energy carried by these photons. For example, the first gravitational waves ever observed were produced by a black hole collision that emitted about 5.3 ×10 47 joules of gravitational-wave energy. The term "radiant energy" also applies to gravitational radiation. In the past, the term "electro-radiant energy" has also been used. In modern applications involving transmission of power from one location to another, "radiant energy" is sometimes used to refer to the electromagnetic waves themselves, rather than their energy (a property of the waves). The term "radiant energy" is most commonly used in the fields of radiometry, solar energy, heating and lighting, but is also sometimes used in other fields (such as telecommunications). This radiation may be visible or invisible to the human eye. The term is used particularly when electromagnetic radiation is emitted by a source into the surrounding environment. In branches of physics other than radiometry, electromagnetic energy is referred to using E or W. The symbol Q e is often used throughout literature to denote radiant energy ("e" for "energetic", to avoid confusion with photometric quantities). The quantity of radiant energy may be calculated by integrating radiant flux (or power) with respect to time. In physics, and in particular as measured by radiometry, radiant energy is the energy of electromagnetic and gravitational radiation. Visible light such as sunlight carries radiant energy, which is used in solar power generation.
