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.
Wave Velocity vs Wave Frequency. Wave velocity and wave frequency are two very important properties of a wave. The wave velocity describes how fast the energy is propagating. The wave frequency describes how fast the wave is oscillating. Both of these properties are very important in defining and describing the wave. Wave velocity is a property of the medium for a certain type of wave. The wave frequency is a property determined by the frequency of the source. â¢ Wave frequency stays constant regardless of the medium the wave is travelling on. Wave velocity changes with the medium.
