= Solution

Since <tension> is a <force> and $\lambda_0$ is a <linear mass density>,
$$
[c]^2=\frac{\mathrm{kg\,m\,s^{-2}}}{\mathrm{kg\,m^{-1}}}
=\mathrm{m^2\,s^{-2}}.
$$
Thus \b[$c$ has units $\mathrm{m\,s^{-1}}$]. It is the transverse <wave speed> of the ideal uniform string. The <wave equation on a string> assumes small transverse slopes, constant positive <tension>, positive uniform <linear mass density>, and negligible <damping> and bending stiffness.
