The two nearest harmonics of a tube closed at one end and open at other end are \(220\,\, Hz\) and \(260\,\, Hz.\) What is the fundamental frequency of the system .... \(Hz\) ?
- A \(10\)
- B \(20\)
- C \(30\)
- D \(40\)
Answer & Solution
Correct Answer
(B) \(20\)
Step-by-step Solution
Detailed explanation
Nearest harmonics of an organ pipe closed at one end is differ by twice of its fundamental frequency.
\( 260 - 220 = 2v, v = 20\ Hz\)
\( 260 - 220 = 2v, v = 20\ Hz\)
