Definition of intensity physics
WebFlux describes any effect that appears to pass or travel (whether it actually moves or not) through a surface or substance. Flux is a concept in applied mathematics and vector calculus which has many applications to physics.For transport phenomena, flux is a vector quantity, describing the magnitude and direction of the flow of a substance or property. In … 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 … 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
