In physics, the intensity or flux of radiant energy is the power transferred per unit area, where the area is measured on the plane perpendicular to the direction of propagation of the energy. In the SI system, it has units watts per square metre (W/m ), or kg⋅s in base units. Intensity is used most frequently with … See more In photometry and radiometry intensity has a different meaning: it is the luminous or radiant power per unit solid angle. This can cause confusion in optics, where intensity can mean any of radiant intensity, luminous intensity See more • Field strength • Sound intensity • Magnitude (astronomy) See more WebApr 8, 2024 · Luminous Intensity is a measure of the wavelength-weighted power radiated by a light source in a particular direction per unit solid angle. It is based on the luminosity function, a standard model of the sensitivity of the human eye. The SI unit of luminous intensity is the candela or cd, it is an SI base unit.
