Answer:
Frequency of the sound wave will be 438.61 Hz
Explanation:
We have given wavelength of the sound wave [tex]\lambda =0.782m[/tex]
Speed of the sound wave v = 343 m/sec
We have to find the frequency of the sound wave
We know that speed of the sound wave is given by [tex]v=\lambda f[/tex], here v is velocity, [tex]\lambda[/tex] is wavelength and f is frequency
So frequency f [tex]=\frac{v}{\lambda }=\frac{343}{0.782}=438.61Hz[/tex]
