Si units for waves
WebbThe units of S are J/ (m 2 s). μ 0 is a constant called the permeability of free space, μ 0 = 4π*10 -7 N/A 2. Note: The energy transported by an electromagnetic wave is proportional to the square of the amplitude, E 2, of the wave. The Poynting vector is the energy flux vector. It is named after John Henry Poynting . WebbThe universal constants appearing in the equations (the first two ones explicitly only in the SI units formulation) are: the permittivity of free space, ε0, and the permeability of free space, μ0, and the speed of light, Differential equations [ edit] In the differential equations,

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 such as acoustic waves (sound) or electromagnetic waves such as light or radio waves, in which case the average power transfer over one period of the wave is used. Intensi…
