No. The fact that waves do not have an effect on other waves does not
mean that their fields don't superpose.

Superposition is a mathematical as well as physical operation. You
maintain that the process of adding x to y must somehow change x and
y. You insist that superposing x and y means that x effects change to
y, and y effects change to x. But the process of superposing x and y
does not have an effect on either x or y. The only effect is we now
have the algebraic sum of x and y.

It has been pointed out to me that Cecil has never used the word
'must' in the context of the above discussion. I will now rewrite my
article deleting the controversial entry . Hopefully the idea that
'waves can interact' can be safely inferred from Cecil's strenuous
argument against the report that waves don't interact.

incorrectly.]

Because of the fact that the word interact means 'to act upon one
another', your assertion that waves can interact means
x can effect change to y, and y can effect change to x.

Since you insist that waves can have an effect on other waves, then
you should at least be able to detail either mathematically or
phenomenalogically the effect y has on x, and x has on y as well as
provide some natural process that would cause this effect. Please
elaborate. Thanks.
