Travelled distance of a wave per time
Property of the medium (determined by the restoring force and the inertia)

$$\begin{array}{rl}v& =\sqrt{\frac{F_{\text{restoring}}}{I}}\\ v& =\frac{\lambda }{T}\\ v& =\lambda f\end{array}$$

For a wave propagating along a string under tension:

$$\begin{array}{rl}v& =\sqrt{\frac{T_s}{\mu }}\\ \mu & =\frac{m}{l}\end{array}$$

Where $\mu$ is the linear density in kg/m.

Wave speed != speed of particle
