Intensity in Physics: Definition & Measurement

NettetIn optical physics, the intensity I, e.g. of a laser beam at some location, is generally understood to the optical power per unit area, which is transmitted through an imagined surface perpendicular to the propagation direction. The units of the optical intensity (or light intensity) are W/m 2 or (more commonly) W/cm 2. NettetIntensity is the quantity of energy the wave conveys per unit time across a surface of unit area, and it is also equivalent to the energy density multiplied by the wave speed. It is …
