MCQ
The frequency of a rod is $200 Hz$. If the velocity of sound in air is $340\,m{s^{ - 1}}$, the wavelength of the sound produced is
- A$1.7 cm$
- B$6.8 cm$
- ✓$1.7 m$
- D$6.8 m$
✓
Answer
Correct option: C.
$1.7 m$
c
(c) $\lambda = \frac{v}{n} = \frac{{340}}{{200}} = 1.7\,m$
(c) $\lambda = \frac{v}{n} = \frac{{340}}{{200}} = 1.7\,m$
