Default what happens to reflected energy ?

I'm sorry, Roy, but I never said anything of the sort. Keith
apparently believes that energy waves somehow bounce off a standing
wave node. I am on the opposite side of that argument. I believe that
the forward wave and reflected wave flow right through a standing wave
node. I am on record as saying the only time a reflection occurs is at
a physical impedance discontinuity.

Misdirection is also accusing someone of saying something that they
never said, is a low blow, and is not an ethical act.

If that is true, then why is there a pacemaker warning posted around
many microwave ovens in public places? Doesn't that warning imply that
not all energy is transfered into heat?

Laser light can usually be considered to be coherent light


No. People produce the coherent light in :http://en.wikipedia.org/wiki/File:HalbachArrayFEL.png


You say lasers are not coherent and then post the url containing
"Description: Free Electron Laser Diagram"?

Free electron laser it is a quite different thing than laser.

The free electron laser produces the "laser-like" light:

" As the electrons are undergoing acceleration they radiate electromagnetic
energy in their flight direction, and as they interact with the light
already emitted, photons along its line are emitted in phase, resulting in a
"laser-like" monocromatic and coherent beam". From:

Mirrors are not perfect.

Air particles move with the speed temperature dependent.
Electrons do the same.

you can do better than that, you just aren't being any fun now!


I do my best.

May be the Wiki is better: "The electron temperature of a plasma can be
several orders of magnitude higher than the temperature of the neutral
species or of the ions. This is a result of two facts. Firstly, many plasma
sources heat the electrons more strongly than the ions. Secondly, atoms and
ions are much heavier than electrons, and energy transfer in a two-body
collision is much more efficient if the masses are similar."

You know: The Sun produces the plasma (it rotate with the Sun) and the
plasma is a medium for the longitudinal electric waves (Tesla - the father
of the radio). Is not it funny?

When is a laser not a laser? When it is a free electron laser.
Unfortunately, I understand completely.

Moral: One should never use the word "all" when describing
imperfection.

I swear I never read Cecill say such things!, Cecil's sin is conspire
to arrange a coup d'état to overthrow collegiate government of
physical duality to place photons at the imperial power :)
