An open pipe immersed in water to half its length. The ratio of the fundamental frequency of the pipe before and after immersion in water is
- A \(1: 2\)
- B \(1: 1\)
- C \(1: 3\)
- D \(1: 4\)
Answer & Solution
Correct Answer
(B) \(1: 1\)
Step-by-step Solution
Detailed explanation
Let \(L_{o}\) be the length of air column in pipe. After immersion, \[ L_{c}=\frac{L_{0}}{2} \] Fundamental frequency in open pipe, \(f_{o}=\frac{v}{2 L_{0}}\) Fundamental frequency in closed pipe, \(f_{c}=\frac{v}{4 L_{c}^{r}}\)…
