Radiation cancellation = destructive interference.

|destructive interference| = |constructive interference|

constructive interference = gain

I do not view Newtons law that way at all
First of all," energy cannot be created or destroyed " which puts"
destructive" as an obsolete word
When Newton espoused his action and reaction law he had equilibrium
very much in mind
His law refers to an "action" as opposed to a "force" so when he
refered to an action it was to the neutralization of force
which in his thinking was stabalization or equilibrium . He then went
on to talk about an equal and opposite reaction.
He was referring to a similar action at right angles to the line of
the first action. Thus, if you pull a piece of rubber thinning or
"necking" occurrs because of the "reaction" required for
stabalization. In a helicoptor you have a big rotor on top that is an
"action", the reaction that Newton talks about is the other action
needed for stabalization which is the rear rotor that is at right
angles to the main rotator. Newton looked at things as three
dimensional and not as a single plain of freedom as with two colliding
forces. He was very specific in stating "action" and not the term
"forces" the same fashion as Maxwell and others refer to a static
field and a dynamic field. From my mind destructive interference
refers to a frictional action that is visible to the eye.
It is these mangling of words in the different sciences that allow
people to thinks that all sciences have their own laws without
connection to a Universal Law which by necessity must be founded on
equilibrium. In our Universe you cannot have a immovable contact
unless there is a interlocking or frictional force. In other words,
two forces cannot travel in a straight line towards each other. Both
force paths are curvacious with respect to the Universe such that the
impact is always one of deflection. But then Cecil you knew all that
didn't you !
Different subject Einstein viewed ether as unthinkable because of
equilibrium which is the foundation of boundary theory where all
forces within the boundary equals the forces outside the arbritary
boundary. Einstein realized that if the forces were not equal or in
equilibrium the field must change from a static to a dynamic field
where implosion is the only way to re establish equilibrium. Plain
common sence don't you think?
