Radiant intensity — In radiometry, radiant intensity is a measure of the intensity of electromagnetic radiation. It is defined as power per unit solid angle. The SI unit of radiant intensity is watts per steradian (W·sr 1). It is distinct from intensity defined by… … Wikipedia
Intensity (disambiguation) — Intensity is a widely used term, which can refer to:In colloquial use: *Strength *Amplitude *Level *MagnitudeIn physics: *Intensity (physics), power per unit area (W/m2) *Field strength of electric, magnetic, or electromagnetic fields (V/m, T,… … Wikipedia
Radiant energy — Visible light (a form of radiant energy) scattered by fog in a forest. Radiant energy is the energy of electromagnetic waves.[1] The quantity of radiant energy may be calculated by integrating radiant flux (or power) with respect to time and … Wikipedia
Intensity (physics) — In physics, intensity is a measure of the time averaged energy flux. The word intensity here is not synonymous with , , or , as it sometimes is in colloquial speech. For example, the intensity of pressure is meaningless, since the parameters of… … Wikipedia
Candela per square metre — Nit (unit) redirects here. For the unit of information entropy, see Nat (information). The candela per square metre (cd/m2) is the derived SI unit of luminance. The unit is based on the candela, the SI unit of luminous intensity, and the square… … Wikipedia
Lumen (unit) — The lumen (symbol: lm) is the SI unit of luminous flux, a measure of the perceived power of light. Luminous flux differs from radiant flux, the measure of the total power of light emitted, in that luminous flux is adjusted to reflect the varying… … Wikipedia
