Learn With Aura on Instagram: "Phase velocity refers to the speed at which a specific point of constant phase on a wave, such as a crest, a trough, or any other identifiable part, travels through space. It essentially measures how fast a particular 'feature' of the wave propagates through the medium. The formula for phase velocity is expressed as v = ω/k. In this equation, 'ω' (omega) represents the angular frequency of the wave, which indicates how rapidly the wave oscillates or completes a cyc
