How about: A photon (particle) traveling at the speed
of light causes shock waves in the aether which, when
passed through double slits, causes interference?


Impossible for empty space - but we now know that space
is not empty. :-) Quoting "Alpha and Omega", by Seife,
"Empty space is an incredibly complex substance, and
scientists are just beginning to understand its properties."

Hello Cecil,


I don't believe you can compare the two phenomena.


The photons are created because of an accelerating charge (so the
photon is the wave itself, not the source that created the wave).


Does the wave have energy?

Hint: The correct answer will tell you if the photon has mass.

Hello,

I am not a specialist in relativity. The EM shock wave generated by
the particle with rest mass (for example electron) entering a medium
with c v(particle) contains energy, but as far as I know, the photon
has no rest mass, it carries momentum. It can therefore exert a force
on an object (radiation pressure in classic electromagnetic theory).
