Derive speed of sound

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. WebThe formula of the speed of sound formula is expressed as. c = γ × P ρ. Where. P = pressure. ρ = density. γ = Ratio of specific heat. Example 1. The sound wave with …
