NettetLuminous Power Per Unit Area of Surface. (Illuminance) The power per unit area on an illuminated surface, sometimes called areance, is distinguished from the similar quantity for the source. In radiometry the surface areance may be called irradiance and luminous areance may be called illuminance. This is the quantity of practical importance in ... NettetSince energy is conserved and the area through which this energy is transported is increasing, the intensity (being a quantity that is measured on a per area basis) must decrease. The mathematical relationship between intensity and distance is sometimes referred to as an inverse square relationship.

NettetThe SI unit of power is the watt, the SI unit of area is the square meter, so the SI unit of intensity is the watt per square meter — a unit that has no special name. intensity … NettetIn part (a), we can find intensity from its definition as power per unit area.
