Others on this newsgroup have admonished me for worrying about
energy and refused to discuss the subject. I thought you were
doing the same. Sorry. But do you actually have any references
that contradict "Optics", by Hecht?

In Dr. Best's article, he superposes V1 with V2 such that constructive
interference energy is needed to complete the superposition. On this
newsgroup, I asked Dr. Best where that necessary constructive interference
energy comes from and he didn't know. That's when I went searching for
references and found them in the field of optics.

Constructive interference energy can be supplied by local sources
as occurs in W7EL's "Food for Thought #1" with its DC example. Or
constructive interference energy can be supplied at a point away
from the source(s) by destructive interference, e.g. wave cancellation
at the non-reflection surface of a layer of thin-film on glass or
at a match point in a transmission line.
