However, two EM waves have to exist before they can cancel.

And that makes rocks like waves?

That makes real waves tangible like real rocks. The wave particles
are just smaller. OTOH, "People who live in glass houses shouldn't
throw stones." is an intangible.

If they exist, they posses both energy and momentum.

Bet ya can't prove it without first transfering it to something.

_Optics_, by Hecht is good enough for me. "It is possible
to compute the resulting (momentum) force via Electromagnetic
Theory, whereupon Newton's Second Law suggests that the *wave

Excellent, now try and understand what is intended by _ALL_ of the words
in the sentence.

Maxwell showed, the *radiation pressure* equals the energy density
of the EM wave. ... When the surface under illumination is perfectly
reflecting, the beam that entered with a velocity of +c will emerge
with a velocity of -c. This corresponds to twice the change in
momentum that occurs on absorption, ..."

Yes, I'm familiar with the subject. I've been familiar with it for a
long time.
However it is incorrect to infer that interactions between waves would
be the same as interactions between waves and matter!

It's obvious that the energy in the TV ghosting wave makes a round-
trip to the match-point and back to the RCVR.

It's obvious that the signal has taken multiple paths, at least.

That's obviously a
change in the direction of momentum of the reflected wave.

Perhaps. You're describing back scattering, which should exhibit a
Compton effect wavelength shift if true. But again, you're describing
an interaction with matter. Photons don't interact with each other in
the same way they interact with matter.
