3. The electric field is either 0 or 180 degrees apart from the
magnetic field. I proved that with math equations in an earlier
posting which I invited you to disprove and you declined. Hint:
see R&W quote below. The pure standing wave Poynting vector is
known to be zero. The only way for that to happen (when E and H
are both not zero) is for the E and H vectors to be mutually
parallel, i.e. 0 or 180 degrees apart.


Oops, I am afraid I must retract my previous congratulatory progress
report. You are obviously still confusing phasors with field vectors.
Until you get that terrible misconception sorted out, there is no hope
for further progress.

I assume that Hecht covers the equations and such. I am sure that Born
and Wolf cover this subject in detail. Check out page 277 in the 6th
edition or page 308 in the 7th edition. You will quickly observe that
the H-field is always perpendicular (90 degrees) to the E-field, even
for standing waves. There is no "0 or 180 degrees" involved.

Is there anything else you plan to teach me about physics? There is
still a whole lot I don't know. I think I may seek out another source,
however.
