The mass of a string is 6.8 x 103 kg, and it is stretched so that the tension in it is 210 N. A transverse wave traveling on this string has a frequency of 190 Hz and a wavelength of 0.67 m. What is the length of the string?

v = sqrt(T/m₀) =sqrt(TL/m)
λ =v/f => v= λf
(λf)²=TL/m
L=(λf)²m/T 
thank you
