If $n_1, n_2$,and $n_3$ are the fundamental frequencies of three segments into which a string is divided,then the original fundamental frequency $n$ of the string is given by

  • A
    $n = n_1 + n_2 + n_3$
  • B
    $\frac{1}{n} = \frac{1}{n_1} + \frac{1}{n_2} + \frac{1}{n_3}$
  • C
    $n = \frac{n_1 n_2 n_3}{n_1 n_2 + n_2 n_3 + n_3 n_1}$
  • D
    $\frac{1}{n^2} = \frac{1}{n_1^2} + \frac{1}{n_2^2} + \frac{1}{n_3^2}$
