Speed of a wave on a string

  1. Jan 13, 2008 #1
    1. The problem statement, all variables and given/known data

    The mass of a string is 9.00 10-3 kg, and it is stretched so the tension in it is 120 N. A transverse wave traveling on this string has a frequency of 260 Hz and a wavelength of 0.60 m. What is the length of the string?

    2. Relevant equations
    1)velocity = frequency*wavelength
    2)velocity = sqroot(F/(m/L))

    3. The attempt at a solution

    I thought i needed to calculate the velocity first, so I used the frequency of 260 * wavelength of .6 and got 156 m/s...then I plugged that in for v into the second equation and also 9.00E-3 as the mass and F is equal to the 120 ...what am I doing wrong, I tried solving for L?

    Looks like you are correct so far... why do think you are wrong?
    Just solve for L, being careful to treat the velocity correctly...
