Question:medium
A pipe open at both ends has a fundamental frequency \(f\) in air. The pipe is now dipped vertically in water drum to half of its length. The fundamental frequency of the air column is now equal to:

Show Hint
Remember the fundamental frequencies for open and closed pipes. For an open pipe of length \(L\), \(f = v/(2L)\). For a closed pipe of length \(L\), \(f = v/(4L)\). When an open pipe is half-submerged, it effectively becomes a closed pipe of half the original length.

- \( f \)
- \( \frac{3}{4} f \)
- \( 2f \)
- \( \frac{1}{2} f \)
