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. WebIn other words, the speed of sound is of the same order of magnitude as the speed of the molecules, and is actually somewhat less than this average speed. Of course we could …
