Energy in em waves
WebThe energy carried by any wave is proportional to its amplitude squared. For electromagnetic waves, this means intensity can be expressed as I ave = cϵ0E2 0 2 I … WebThe ratio of the electric to magnetic fields in an electromagnetic wave in free space is always equal to the speed of light. This knowledge can then be used to simplify the energy density situation a bit. Start with the magnetic energy density and replace it with an expression containing the electric field.
