WebMay 9, 2024 · Phase velocity is the speed at which a point of constant phase travels as the wave propagates. 1 For a sinusoidally-varying wave, this speed is easy to quantify. To see this, consider the wave: Acos(ωt − βz + ψ) where ω = 2πf is angular frequency, z is position, and β is the phase propagation constant. WebFigure 3.6 In a graph of position versus time, the instantaneous velocity is the slope of the tangent line at a given point. The average velocities v – = Δ x Δ t = x f − x i t f − t i between times Δ t = t 6 − t 1, Δ t = t 5 − t 2, and Δ t = t 4 − t 3 are shown. When Δ t → 0, the average velocity approaches the instantaneous ...
