When a string is divided into three segments of
lengths `l_(1),l_(2) and l_(3)` the fundamental frequencies of
these three segments are `v_(1), v_(2) and v_(3)` respectively.
The original fundamental frequency (v) of the string is

Options

A. `sqrtv = sqrtv_1 + sqrtv_2 + sqrtv_3 `
B. `v= v_1 + v_2 + v_3`
C. `1/v = (1)/(v_1) + (1)/(v_2) + (1)/(v_3)`
D. `(1)/(sqrtv) = (1)/(sqrtv_1) + (1)/(sqrtv_2) + (1)/(sqrtv_3)`

Answer

C
