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 … 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 NettetPhysical Intensity Calculator Anzeige Physical quantities: Force Work Power Pressure Density Velocity Acceleration Momentum Torque Intensity Exergy Charge …
16.4 Energy and Power of a Wave - OpenStax
NettetIntensity (I) = Power × [Area]-1. Or, I = [M 1 L 2 T-3] × [M 0 L 2 T 0]-1 = [M 1 L 0 T-3] Therefore, the time period is dimensionally represented as [M 1 L 0 T-3]. ⇒ Check … rainton grove
