The fundamental frequency of a closed tube is the same frequency as the 2nd harmonic of a stretched string. The mass per unit length of the string is 6.10×10-4 kg/m. The tension in the string is 48.0 N. What is the ratio of the length of the string to the length of the closed tube Ls/LT? (Write your answer as a number. For example, if Ls= 1 and LT = 2, write 0.5. Units are not required.)
