Web47–5 The speed of sound. Our deduction of the wave equation for sound has given us a formula which connects the wave speed with the rate of change of pressure with the density at the normal pressure: c2s = (dP dρ)0. In evaluating this rate of change, it is essential to know how the temperature varies. WebProperties of the medium that affect wave speed: Density: is the mass per unit of volume of the medium. A medium’s density is determined by the closeness of its particles and the weight of individual particles. Temperature: the average kinetic energy of the particles or on average how fast particles move. Elasticity: ability of a deformed material body to return …
