A cylindrical tube open at both ends has a fundamental frequency 'f' in air. The tube is dipped vertically in water so that half of it is in water. The new fundamental frequency is
- A f
- B \(\frac{f}{2}\)
- C 2f
- D 4f
Answer & Solution
Correct Answer
(A) f
Step-by-step Solution
Detailed explanation
Initially \[ \mathrm{f}=\frac{\mathrm{V}}{2 \ell} \] Finally From diagram, we can see \[ \begin{aligned} & \frac{\lambda}{4}=\frac{\ell}{2} \\ & \Rightarrow \lambda=21 \end{aligned} \] Now, fundamental frequency…
