The equation for wave speed is:
[tex]v=\lambda * f[/tex]
where "v" is wave speed, "λ" is wavelength and "f" is frequency.
Given the wave speed is 343m/s and the wavelength is 0.77955m, we can rewrite the equation as:
[tex] \frac{v}{\lambda} = f[/tex]
Substituting known values, we get:
[tex] \frac{343}{0.77955} =f[/tex]
[tex]f=439.9974344[/tex]
The pitch that's the closest to this value is Pitch A.
