Question
A string is cut into three parts, having fundamental frequencies n1, n2 and n3 respectively. Then original fundamental frequency ′n′ related by the expression as (other quantities are identical) : -
Options
A.
B.n = n1 × n2 × n3
C.n = n1 + n2 + n3
D.n = 
Solution
n1l1 = n2l2 = n3l3 = nl
⇒ l1 + l2 + l3 = l ⇒
