The first, and most profound, difference between wave motion and the motion of objects is that waves do not display any repulsion of each other
analogous to the normal forces between objects that come in contact. Two wave patterns can therefore overlap in the same region of space, as shown in
the figure at the top of the page. Where the two waves coincide, they add together. For instance, suppose that at a certain location in at a certain
moment in time, each wave would have had a crest 3 cm above the normal water level. The waves combine at this point to make a 6-cm crest. We use
negative numbers to represent depressions in the water. If both waves would have had a troughs measuring -3 cm, then they combine to make an extradeep
-6 cm trough. A +3 cm crest and a -3 cm trough result in a height of zero, i.e. the waves momentarily cancel each other out at that point. This
additive rule is referred to as the principle of superposition, "superposition" being merely a fancy word for "adding."

Do you know that you proved yourself wrong, in what you thought was proving yourself right? in agrement with other posters, is this the level of
intelligence on here? wow.
First off, Lets give you the benefit of the doubt, and say that a wave = an earthquake.
If you read what you posted, a 3 foot wave running into a 3 foot wave, creates a 6 foot wave.
A wave 3 feet below sea level (or -3) running into another -3, creates a -6 foot wave (or a dip in water 6 feet below sea level)...
Now, replace the words wave with earthquake above. Are you saying that every time, a +3 earthquake would be running into a -3 earthquake, thus
canceling them out? Thats amazing, that they can get the positivity of an earthquake, to match the negativity of the earthquake its about to run
you might say "wait, wait, i meant earthquakes have waves in the same way a body of water does, not a single wave equalling a single earthquake."
ok, fine, sorry. that would be even more unbelievable. That would mean that the wave patterns of the two colliding earthquakes would have to be exact
oposites of each other, in a mirrored fashion, in such precise timing and accuracy as to completely cancel each other out at point of collision.
This is the same website that complains about news stations and the media taking things out of context to prove their own point. At least the news
stations have enough sense to cut out the rest of the video. Where as you, left it in your source text for everyone to see.
we are all now dummer for reading this. you are awarded no points, and may your god have mercy on your soul.
