I guess you didn't notice the thing about the square of the sum of two
numbers being four times as great as the square of one of the numbers.
It simply means, for example, that a doubling in voltage is a
quadrupling in power. It doesn't mean there's "extra" energy anywhere.

The "extra" energy in the bright
rings comes from the dark rings.

There really is no extra energy.

The conservation of
energy principle allows nothing else.

Conservation of energy doesn't allow for there to *be* extra energy in
the first place! That's the most fundamental principle. Putting the
word 'extra' in quotes doesn't change that.

It is not a
sophomoric notion.

The notion was apparently contrived so that sophomores wouldn't feel
the need to ask as many questions.

It is the laws of physics in action.

As far as you know.
