Brightness physics
Did you know?
WebThe brightness (more properly known as the specific brightness) is the intensity of a radiating source (i.e., the energy flux per solid angle per unit of frequency), also called the radiance or surface brightness. In MKS, it is measured in units of . The total power passing a given surface is then given by. where is the angle to the normal, dA ... The lumen (symbol: lm) is the unit of luminous flux, a measure of the total quantity of visible light emitted by a source per unit of time, in the International System of Units (SI). Luminous flux differs from power (radiant flux) in that radiant flux includes all electromagnetic waves emitted, while luminous flux is weighted according to a model (a "luminosity function") of the human eye's sensitivity to various wavelengths. One lux is one lumen per square metre.
