The last paragraph above is a perfect example of your tendancy to
misinterpret these texts, Cecil. Born and Wolf does not (and would not)
assert that there is "no effect" when mutually incoherent waves are
superposed. It's not reasonable to say that. There is certainly an
effect. In fact Walt and I use the effect whenever we tune our basses.
One wave has no effect on the other wave, Jim.
Please pay attention.
