Intensity from electric field
Webwell, when it comes to electric fields, and specifically this formula E=k*Q/r^2, its best that you leave positive and negative out of the formula because we have established a new system of directions here. which is shown in earlier videos. WebOnce the intensity is known, we can use the equations below to find the field strengths asked for in Parts 2 and 3. Solution for Part 1 Entering the given power into the definition of intensity, and noting the area is 0.300 by 0.400 m, yields I = P A = 1.00 kW 0.300 m×0.400 m I = P A = 1.00 kW 0.300 m × 0.400 m Here I = Iave, so that

WebMay 17, 2024 · The intensity is defined as power per unit area, and power is defined as energy per unit time. Thus: I = P A = E Δ t 1 A. The energy of a photon is E = h f, so the total intensity for n photons is I = n ⋅ h f A Δ t. In this model, photons are only counted, and not seen as waves. Thus there is no amplitude to be considered. Share Cite
