The "absence of energy flow" is an illusion. There is 100
joules/sec in the forward wave and 100 joules/sec in the
reflected wave. Since the waves are flowing in opposite
directions, you can argue that there is no *net* energy
flow, but the component wave energy flow is alive and well.

Cecil,

You have made this claim about "component wave energy flow" or a similar
claim on numerous occasions. However, only a few minutes after the
message above, you wrote,

"Power and energy are scalars, Roy. Of course, scalars follow
different rules. Maybe the problem is that you are trying
to use phase math on power."

Help me out. How can we have scalars flowing in opposite directions? If
the waves can interact, as you claim, why does the associated energy
fail to interact and merely pass like ships in the night?

Conservation of energy does not really help the explanation in this
case, as your recently discovered new reference, Principles of Optics by
Born and Wolf, points out.
