Suppose that a guitar string has a length of 1.1 m, a mass of 0.12 kg and a tension of 125 N. 
   What is the speed of the wave on the string?

apoorvk · Answer

wave speed 'v' --->

$$v = \frac{\sqrt{T}} {\sqrt{mu}}$$
where,
T=tension
mu=linear mass density (i.e. mass per unit length of the wire)

apoorvk · Answer

that means, mu=mass/length

anonymous · Answer

Hi
you can use from this:
$$v=\sqrt{T/\lambda }$$ where 
lambda is mass per meter
