what is propagation in physics

Propagation in physics refers to the movement of waves, such as electromagnetic or sound waves, through space or a physical medium. It is the process by which a disturbance is transmitted from one point to another. In other words, it is the way in which waves spread out and travel from their source to other locations. The term wave propagation is used to describe the movement of waves, which have frequency, amplitude, wavelength, and wave speed. In physics, propagation is an important concept that helps to explain how waves behave and interact with their environment.
