Homework Help: Speed of transverse string waves

  1. Nov 13, 2007 #1
    A piano string of length 1.5 m and mass density 25mg/m vibrates at a (fundamental) frequency of 460 Hz.
    What is the speed of the transverse string waves?

    v=sqrt (FL/m)

    v= sqrt (37.5*1.5/25)

    is this the right track?

    I would try using the equation:

    [tex] v=\lambda f[/tex]

    You know f already. All you need then, is the wavelength,[tex]
    \lambda[/tex]. You know the wave is vibrating at a fundamental frequency. Does this tell you anything about the wavelength of that wave?
