Understanding Wave Motion: Types and Properties
Waves move up and down any object, but not in the direction in which the waves are advancing. When at rest, the object is in its initial position. Wave motion is a form of power transmission, with no net transport of material, through the propagation of any form of disturbance. This disturbance is called a wave. In any wave propagation phenomena, we can see some common elements:
- An initial perturbation that is transmitted to other points, with no net movement of matter.
- A transmission of energy through
