Intensity light equation
NettetIn equation form, intensity I is I=PA I = P A , where P is the power through an area A. The SI unit for I is W/m 2. What is the intensity of light? Light intensity refers to the strength or amount of light produced by a specific lamp source. It is the measure of the wavelength-weighted power emitted by a light source. 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 waves … Se mer 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 Se mer • Field strength • Sound intensity • Magnitude (astronomy) Se mer
