A sound wave in the air has a frequency of 256 hertz and is traveling at a speed of 331 meters/second. What is its wavelength?1.52 meters1.29 meters2.39 meters0.500 meters10.0 meters

Respuesta :

Explanation

the velocity of the wave is given by:

[tex]v=f\lambda[/tex]

where

v is the velocity of the wave, f is and \lambda is the thquency wavelength oof f thewave

then , let

[tex]\begin{gathered} v=331\text{ }\frac{m}{s} \\ f=2556\text{ Hz} \\ \lambda=\lambda \end{gathered}[/tex]
