In physics, a wave is an oscillation accompanied by a transfer of energy that travels through space or mass. Frequency refers to the addition of time. Wave motion transfers energy from one point to another, which may or may not displace particles of the medium âthat is, with little or no associated mass transport.n other words, the velocity of the constituent waves of the wave packet travel at a rate that varies with their wavelength, so some move faster than others, and they cannot maintain the same interference pattern as the wave propagates.
A wave is defined as a disturbance which is moved medium; for example, the wave of the ocean moves in medium water and we can see the movement of wave crest from one side to the other side in a given time period.The motion of objects is described in terms of speed which shows the fastness of the object.S_{W}$= speed of the wave. $D_{W}$ = distance travelled by crest or trough of the wave. T = time taken to travel the distance $D_{W}$. This equation is the speed of any particle according to the classical theory of physics and it is equally applicable to the waves due to their dual nature.
