JEE Mains · Physics · STD 11 - 14. waves and sound
In a resonance tube experiment when the tube is filled with water up to height of \(17.0\, cm\) from bottom, it resonates with a given tuning fork. When the water level is raised the next resonance with the same tuning fork occurs at a height of \(24.5\, cm\). If the velocity of sound in air is \(330\, m / s ,\) the tuning fork frequency is\(......Hz\)
- A \(1100\)
- B \(3300\)
- C \(2200\)
- D \(550\)
Answer & Solution
Correct Answer
(C) \(2200\)
Step-by-step Solution
Detailed explanation
\(\Rightarrow \lambda=2\left(l_{2}-l_{1}\right) \Rightarrow 2 \times(24.5-17)\) \(\Rightarrow 2 \times 7.5=15 cm\) \(\& v = f \lambda \Rightarrow 330=\lambda \times 15 \times 10^{-2}\) \(\lambda=\frac{330}{15} \times 100 \Rightarrow \frac{1100 \times 100}{5}\)…
