Is the power in an electromagnetic wave equally transferred along both the electric and magnetic fields?
YesIs the power in an electromagnetic wave equally transferred along both the electric and magnetic fields?
I now think (a) is not accurate because of the word "along", as it should say "by".option (b) does not specify what exactly are the fields. It just mentions it as both the fields. so i think that (a) is more accurate.
The wording suggests that power flows along the field lines, which is not correct.does'nt option (a) suggest that energy is equally divided between the electric and magnetic fields?
When there are viscous forces, work is done on regions of the medium and is not retrieved. In that case, there will be a net transverse work done during each half cycle.viscous forces
If you are dealing with EM, I have to ask you what transverse momentum? The momentum is in the longitudinal direction, surely.I agree with Sophie (perhaps I never should have brought up the water analogy). Nevertheless, momentum is transferred sideways.
