In classical physics, waves are described by properties such as position, velocity, and other characteristics. However, it's important to note that waves do not possess the same type of localized, tangible existence as particles. The concepts of position and velocity in the context of waves are slightly different from those associated with particles.
In wave theory, the position of a wave refers to the location of a particular point on the wave at a given instant in time. For example, if you consider a water wave, you can identify the position of a crest or trough of the wave at any moment.
Velocity, on the other hand, refers to the speed and direction at which the wave propagates through a medium. It represents how fast the disturbance associated with the wave is moving from one point to another. The velocity of a wave is determined by its wavelength and frequency. The wavelength is the distance between successive crests or troughs of the wave, while the frequency is the number of crests or troughs passing a fixed point per unit of time.
In the case of waves, it's important to understand that they are not localized entities like particles. They are distributed phenomena that propagate through a medium. While waves have a position associated with different points on the wave, they do not have a single, well-defined position like a particle does.
So, in summary, waves have a notion of position that corresponds to different points on the wave, but their velocity describes how the disturbance associated with the wave propagates through the medium, rather than the movement of a localized entity.
