How Do You Calculate Wave Speed on a String?

[semc]

A string of density $$\mu$$=0.09 kg/m is under tension of 110N. A force is supplied to the string to generate a sinusoidal wave at frequency of 100Hz and amplitude of 4.5cm. What is the speed of wave on the string?

I am wondering if I can get the speed of the wave on the string by using v=(T/$$\mu$$)? If that is the case, what is the frequency and amplitude use for?

Probably the small amplitude tells that the tension is constant.
