Radiant Power - The time rate of flow of radiant energy. Units-watts. (One [1] watt = 1 Joule-per-second). The rate of emission of transmission of radiant energy.
the rate of flow of radiant energy (electromagnetic waves)
The amount of power incident on a given surface expressed in watts.
a measure of radiometric power. Radiometric flux, expressed in watts, includes light at all wavelengths of the spectrum; ultraviolet (200 to 400 nm), visible (400 to 700 nm), and infrared (700 to 30000 nm).
Total energy radiated in all directions from an object per unit time; sometimes referred to as radiant power. Standard measurement unit W.
The rate of energy transfer by electromagnetic radiation, in units of energy per unit time. Denoted by F = dQ/dt and measured in MKS units as Joules/second or Watts.
(Sometimes called hemispheric flux.) Radiant energy per unit time passing some specified area from one side; units are watts
In radiometry, radiant flux or radiant power is the measure of the total power of electromagnetic radiation (including visible light). The power may be the total emitted from a source, or the total landing on a particular surface.
