Em wave change
WebThe radiation field E rad produce by accelerating charges decreases as 1/r. Since the intensity is proportional to E rad 2, the intensity of the radiation very far from a localized source therefore decreases as 1/r 2, where r is the distance from the source.Energy is conserved. As the EM wave propagates away from the source, its spreads its energy … WebElectromagnetic waves are similar, but they are also distinct in that they actually consist of 2 2 2 2 waves oscillating perpendicular to one another. One of the waves is an oscillating magnetic field; the other is an …
