What is the frequency of a sound wave having a velocity of 341 meters/second and a wavelength of 0.8 meters? 426 hertz 400 hertz 800 hertz 210 hertz

$\text{426 Hz}$

Explanation:

Velocity ($\text{v}$), Frequency ($f$) and wavelength (λ) are related as

"v" = f λ

From above

$f = \text{v"/λ}$

$\textcolor{w h i t e}{f} = \text{341 m/s"/"0.8 m}$

$\textcolor{w h i t e}{f} = 426.25 \setminus \text{Hz" ≈ "426 Hz (in 3 sig. fig)}$
