A closed organ pipe has a fundamental frequency of \(1.5\, kHz\). The number of overtones that can be distinctly heard by a person with this organ pipe will be : (Assume that the highest frequency a person can hear is \(20,000\, Hz\))
- A \(6\)
- B \(4\)
- C \(7\)
- D \(5\)
Answer & Solution
Correct Answer
(A) \(6\)
Step-by-step Solution
Detailed explanation
For closed organ pipe, resonate frequency is odd multiple of fundamental frequency. \((2 n+1) f_{o} \leq 20,000\) \(\left(f_{o} \text { is fundamental frequency }=1.5 Khz \right)\) \(n=6\)
