Homework SourseThe mass of a string is 68 x 103 kg and it is stretched so t
The mass of a string is 6.8 x 10-3 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 360 Hz and a wavelength of 0.73 m. What is the length of the string?
Solution
V - Velocity of the wave n - frequency of the wave = 360 Hz
- wavelength of the wave= 0.73 m T - Tension in the string = 210 N
M - Mass of the string= 6.8 x 10-3 kg, L - Length of the string
V=sqrt(T/(M/L))
n=sqrt(TL/M)
L=n22(M/T) = 2.236 meter.
