MHT CET · Physics · Waves and Sound
In fundamental mode, the time required for the sound wave to each upto the closed end of a pipe filled with air is ' \(t\) ' second. The frequency of vibration of air column is
- A \(\frac{2}{t}\)
- B \(\frac{0.5}{t}\)
- C \(\frac{1}{t}\)
- D \(\frac{0.25}{t}\)
Answer & Solution
Correct Answer
(D) \(\frac{0.25}{t}\)
Step-by-step Solution
Detailed explanation
\(\begin{aligned}
& \Rightarrow V=\frac{L}{y}=(4 L) g \\
& \Rightarrow f=\frac{0.25}{t}
\end{aligned}\)
