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?
