If the length of an open organ pipe is \(33.3 \mathrm{~cm}\), then the frequency of fifth overtone is [Neglect end correction, velocity of sound \(=333 \mathrm{~m} / \mathrm{s}\) ]
- A \(3500 \mathrm{~Hz}\)
- B \(3000 \mathrm{~Hz}\)
- C \(2500 \mathrm{~Hz}\)
- D \(2000 \mathrm{~Hz}\)
Answer & Solution
Correct Answer
(B) \(3000 \mathrm{~Hz}\)
Step-by-step Solution
Detailed explanation
For a pipe open at both ends,
\(\mathrm{n}=\frac{\mathrm{v}}{2 l}=\frac{333}{2 \times 33.3 \times 10^{-2}}=500 \mathrm{~Hz}\)
\(\therefore \quad\) Frequency of \(5^{\text {th }}\) overtone,
\(\mathrm{n}=6 \mathrm{n}=6 \times 500=3000 \mathrm{~Hz}\)
\(\mathrm{n}=\frac{\mathrm{v}}{2 l}=\frac{333}{2 \times 33.3 \times 10^{-2}}=500 \mathrm{~Hz}\)
\(\therefore \quad\) Frequency of \(5^{\text {th }}\) overtone,
\(\mathrm{n}=6 \mathrm{n}=6 \times 500=3000 \mathrm{~Hz}\)
