MP Board · Class 9 · Science · SoundA sound wave has a frequency of $500\text{ Hz}$ and a wave speed of $340\text{ m/s}$. Calculate its wavelength.
Step-by-Step Solution
Given:
- Frequency of sound wave ($\nu$) = $500\text{ Hz}$
- Speed of sound wave ($v$) = $340\text{ m/s}$
Formula: $$\text{Speed } (v) = \text{Frequency } (\nu) \times \text{Wavelength } (\lambda)$$ $$\lambda = \frac{v}{\nu}$$
Calculation: $$\lambda = \frac{340}{500} = 0.68\text{ meters}$$
Answer: The wavelength of the sound wave is $0.68\text{ m}$.
