Question

If n 1 , &#160; 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:

Quantrex Academy · Accepted Answer

Correct answer: A. 1 n = 1 n 1 + 1 n 2 + 1 n 3

For first segment we have, n 1 = 1 2 l 1 &#160; T &#956; For second segment we have, n 2 = 1 2 l 2 &#160; T &#956; For third segment we have, n 3 = 1 2 l 3 T &#956; For the whole string we have, n = 1 2 l &#160; T &#956; Total length of the string is, l = l 1 + l 2 + l 3 Thus, the fundamental frequency for the whole string is, 1 n = 1 n 1 + 1 n 2 + 1 n 3

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:
