What is radiant energy and how does it work?

How is radradiant energy measured?

  • Radiant energy is, like most forms of energy, measured in joules and is calculated by integrating the radiant flux (power) of the electromagnetic wave with respect to time. There are two different views of how electromagnetic waves carry energy, and both are considered accurate because of the wave-particle duality concept of quantum theory.

What is the difference between radiant energy and electromagnetic radiation?

  • Analysis. Because 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. Alternatively, EM radiation can be viewed as an electromagnetic wave, which carries energy in its oscillating electric and magnetic fields.

What is the SI unit of energy in radiant energy?

  • As energy, its SI unit is the joule (J). The quantity of radiant energy may be calculated by integrating radiant flux (or power) with respect to time. The symbol Q e is often used throughout literature to denote radiant energy ("e" for "energetic", to avoid confusion with photometric quantities).
