Homework Help: Finding the wave speeds

  1. Feb 1, 2015 #1
    1. The problem statement, all variables and given/known data
    Two steel guitar strings have the same length. String A has a diameter of 0.50 mm and is under 410.0 N of tension. String B has a diameter of 1.0 mm and is under a tension of 820.0 N. Find the ration of the wave speeds, VA / VB
    in these two strings.
    2. Relevant equations
    V= ƒ λ
    FT = FG
    3. The attempt at a solution
    I'm lost on where to start.....:oldcry::oldconfused::oldconfused::oldcry:

    Amongst your standard equations, you should have one that relates wave speed in a string/wire to tension and mass per unit length.

    v=√(T/¢)
    T= tension in wire
    ¢= mass per unit length
