A pipe open at both ends of length 1.5 m is dipped in water at one end such that \(2^{\text {nd }}\) overtone of vibrating air column is resonating with a tuning fork of frequency 330 Hz . The length of the pipe immersed in water is (Speed of sound in air \(=330 \mathrm{~m} / \mathrm{s}\) ) (Neglect end correction)
- A 1 m
- B 0.75 m
- C 0.5 m
- D 0.25 m
Answer & Solution
Correct Answer
(D) 0.25 m
Step-by-step Solution
Detailed explanation
\(f = \frac{5v}{4L_a}\) \(330 = \frac{5 \times 330}{4L_a}\)
