Waves
The previous example of the “marching band wave” illustrates one very important property of waves:
- A wave is a pattern in motion
- The velocity of a wave depends upon the type of wave and the medium through which it is transmitted.
The other property of waves which we will need to understand is the Principle of Superposition:
- The displacement produced by two waves at the same point is merely the sum of the displacements produced by each alone.
