How do you calculate wave speed in linear density?

  • For a string, the formula for wave speed is $v=\\sqrt{\\frac{T}{\\mu}}$, where $\\mu=\\frac{m}{L}$. 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?
