State the relationship between speed, frequency, and wavelength of a sound wave. Calculate the speed if frequency is 2 kHz and wavelength is 0.35 m.

Q: State the relationship between speed, frequency, and wavelength of a sound wave. Calculate the speed if frequency is 2 kHz and wavelength is 0.35 m.

The speed ($v$) of a sound wave is given by the product of its frequency ($\nu$) and wavelength ($\lambda$), i.e., $v = \nu \times \lambda$. Given frequency $\nu = 2000\text{ Hz}$ and wavelength $\lambda = 0.35\text{ m}$. Therefore, the speed of the wave is calculated as $v = 2000 \times 0.35 = 700\text{ m/s}$. The wave travels at 700 meters per second.
