I am genuinely open-minded about that debate - which makes the all the
more determined to be ruthless about bogus arguments on either side.


Ian, correct me if I'm wrong, but I infer that you are biased
toward the "no reflected energy waves" side. That bias could be
based on perceived knowledge.

Seems to me, some people are begging the question. They assume
there is no energy in reflected waves and call what the other
side says, "gobbleygook", even when presented in scientific
terms. I think we all understand the concepts behind net
energy. What is in dispute is the next lower layer of dynamic
energy movement in both directions at the same time during
steady-state.

So would you explain what happens to the reflections of a laser
beam when aimed at a perfect mirror in free space. Offset the
laser beam slightly from normal incidence to start with and
observe the reflections with your naked eye. Then bring the
beam to 90 degree incidence with the mirror. You can no
longer see the reflections but now you can detect the
superposition of the forward and reflected waves through
interference "rings" or loops with an intensity maximum
occuring every half wavelength and an intensity minimum
occuring every half wavelength in between.

Where is the EM wave energy just sloshing around and not
traveling forward and rearward at the speed of light?
