MCQ
The frequency of fundamental tone in an open organ pipe of length $0.48 m$ is $320 Hz.$ Speed of sound is $320 m/sec.$ Frequency of fundamental tone in closed organ pipe will be ... $Hz$
- A$153.8$
- ✓$160.0$
- C$320.0$
- D$143.2$
✓
Answer
Correct option: B.
$160.0$
b
(b) ${n_{{\rm{Closed}}}} = \frac{1}{2}({n_{{\rm{Open}}}}) = \frac{1}{2} \times 320 = 160\,Hz$
(b) ${n_{{\rm{Closed}}}} = \frac{1}{2}({n_{{\rm{Open}}}}) = \frac{1}{2} \times 320 = 160\,Hz$
