The mass of a string is 6.0 x 10^-3 kg, and it is stretched so the tension in it is 195 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?

Isn't wavespeed= sqrt(Tension/(mass/length))

you know wavespeed (wave equation, given f and lambda). You know tension, so solve for mass/length. You know mass, so solve for length.
