Standing electromagnetic waves
Webbwave equation. In Section 8.4 we talk about the energy contained in an electromagnetic wave, and in particular the energy °ow which is described by the Poynting vetor. In Section 8.5 we talk about the momentum of an electromagnetic wave. We saw in Section 4.4 that the waves we’ve discussed so far carry energy but not momentum ... Webb30 juli 2015 · The standing wave solution you quote is a solution to Maxwell's equations - as is any linear superposition of travelling waves. The relationship that E = c B is really only applicable to travelling transverse electromagnetic waves in vacuum, however I note that in this case E 0 = c B 0. The Poynting vector (in vacuum) is defined by S E → × B → μ 0
