Given the power-density equation:

May I assume that from what you have said so far, that P1
and P2 never existed in the first place????

Being an under defined problem, it's difficult to know. But it is
certainly possible that P1, or P2, or both never existed.
Particularly the latter, if the fields happen to be co-located in
space and are at every point equal in magnitude and opposite in phase.

If they never
existed, wouldn't their magnitudes be zero in violation
of every rule of physics concerning reflections????

I assure that no 'physics violations' are implied or intended by
anything I post with my name, callsign, and email address attached to
it. It would not...um.....reflect well. ;-)
