Superposition of wave
Wave will overlap to show the shape of the specific in the place where
the clash, but I'll give away to keep the shape of the original and too
the point.Even after the two waves met, is called the independence of the
wave, the nature forward while maintaining the original shape without being
affected by one another.Where you collide, you can see that it is the form
of the sum of the displacement from the video below.I called the principle
of superposition of waves this property.
