In a resonance tube experiment, a tuning fork resonates with air column of length \(12 \mathrm{~cm}\) and again resonates when air column is \(38 \mathrm{~cm}\) long. The end correction will
(b)
- A \(0.25 \mathrm{~cm}\)
- B \(0.5 \mathrm{~cm}\)
- C \(1 \mathrm{~cm}\)
- D \(0.75 \mathrm{~cm}\)
Answer & Solution
Correct Answer
(C) \(1 \mathrm{~cm}\)
Step-by-step Solution
Detailed explanation
\(e=\frac{l_{2}-3 l_{1}}{2} \quad\therefore e=\frac{38-36}{2}=1 \mathrm{~cm}\)
