Particle velocity
Additional recommended knowledgeParticle velocity should not be confused with the speed of the wave as it passes through the medium, i.e. in the case of a sound wave, particle velocity is not the same as the speed of sound. Equations in terms of other measurementsThe velocity v can be related to the particle displacement ξ and acceleration for single frequency plane wave of frequency f using It is further related to the instantaneous acoustic intensity vector I (not the timeaveraged averaged acoustic intensity) according to
