Yes, but what is the characteristic impedance of free space?

The value has been established; that I am sorely disappointing you has
been established; and that I am content with those outcomes has been
established. Any further interest for others is how long this groupie
drama of betrayed faith will play out.

Question: If photons are stable, chargeless, massless elementary particles,
how do they react with anything?

"Stable" doesn't mean they are inert. Photons are
emitted and absorbed all the time while interacting
with other particles. I believe Hecht means that
photons don't decay over time all by themselves
(but there is some debate on that subject).

I think you will find many examples from radio astronomy
where radio signals are red-shifted just like light.

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).

Best regards,

I understand red-shift in terms of astronomy, but you can never be sure of
all the effect in that situation such as acceleration and gravity. I suggest
that there is no observations of radio signals changing frequency due to
distance under lab conditions, which I still believe would be a relatively
easy test.

So you now agree that I was correct in saying that Zo free space = 377 Ohms
and Roy was wrong in saying it was = 1 Ohm?
You still have a chance to recover your cred, bro.

He didn't. It is most common and evident (meaning you can trust your

Hahahahaha! Thanks, Richard! ;-) I'd been wondering that myself.
