What happens to the energy flowing in the lamp cord when you turn out
your desk lamp? :-)

It still exists. It just ceases to be converted to
heat. Do you believe energy can be destroyed?

We know the EM reflected wave is not converted to
heat. So its energy still exists as EM energy.
Where does that energy go?

Ceci,
If I have a 20 foot barge pole in my hand
and I poke somebody with it heat is generated
at the other end of the pole. There is no energy
left in the pole!
