Homework Help: Determining Tension

  1. Feb 10, 2010 #1
    The question is A harmonic wave in a wire has amplitude 6.32mm, wavelength 2.99m, and frequency 157hz. The propagation speed of the wave is 469.43 m/s
    The wire has a linear mass density of 11 g/m.
    How do I determine the wire's tension?

    I can't figure out what equation to use.

    Hi Seablew4, welcome to PF.
    Velocity in the wire V = sqrt(T/m).
    Neglect the other data.
