TS EAMCET · Physics · Waves and Sound
An organ pipe with both ends open has a length \(L=25 \mathrm{~cm}\). An extra hole is created at position \(\frac{L}{2}\). The lowest frequency of sound produced is (assume, speed of sound \(=340 \mathrm{~m} / \mathrm{s}\) )
- A \(680 \mathrm{~Hz}\)
- B \(340 \mathrm{~Hz}\)
- C \(1360 \mathrm{~Hz}\)
- D \(4352 \mathrm{~Hz}\)
Answer & Solution
Correct Answer
(C) \(1360 \mathrm{~Hz}\)
Step-by-step Solution
Detailed explanation
We know that, there must be an antinode at the open end. Since, a hole has been made at the position \(\frac{L}{2}\), so there must be another antinode at \(x=\frac{L}{2}\). For lowest frequency, \(\lambda=L=25 \mathrm{~cm}\) Frequency of sound produced,…
