```This is why we need to use coloring dye...  :-)

Seriously, I wonder about the particle and
wave duality of electrons.  Remember, the
drift velocity of electrons is not the same
as the propagation velocity of the EM waves.

So what happens at the "collision" point (i.e.
the electrical midpoint of the loop)?  Do=20
the electrons hit each other and bounce back
like balls with the drift velocity speeds,
while at the same time the waves go through
each other (at speeds close to c) without
changing directions?

Another analogy comes to my mind, when two laser
beams on different path cross each other.  After
the cross point we are still going to see their
original colors without any mixing.  However,
if you did the same with two water streams,
the cross point will result in a splash in all
different directions...

Is there someone out there with a good physics=20
background who could shed some light on this?

Thanks,

Arpad

Orin,
Since the reflected and propagated waves have identical properties and=20
are indistinguishable, how can you be sure it is one and not the other?

Thanks,
