NettetDensity and Wave Speed. For a string, the formula for wave speed is v = T μ, where μ = m L. The greater the linear density, the more massive the string is per unit length, the more inertia it has, and the slower the wave propagates. However, for a sound wave, wave speed is fastest in densest media. Why is that the case?
