MCQ
If $v$ is the speed of sound in air then the shortest length of the closed pipe which resonates to a frequency $n$
- ✓$\frac{v}{{4n}}$
- B$\frac{v}{{2n}}$
- C$\frac{{2n}}{v}$
- D$\frac{{4n}}{v}$
✓
Answer
Correct option: A.
$\frac{v}{{4n}}$
a
(a) For shortest length of pipe mode of vibration must be fundamental
(a) For shortest length of pipe mode of vibration must be fundamental
i.e., $n = \frac{v}{{4l}}$==> $l = \frac{v}{{4n}}.$
