Speed of wave on a string

  1. Apr 22, 2010 #1
    A string of density [tex]\mu[/tex]=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/[tex]\mu[/tex])? If that is the case, what is the frequency and amplitude use for?

    Probably the small amplitude tells that the tension is constant.
