The equation for wave speed is:

v=\lambda * f

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:

\frac{v}{\lambda}  = f

Substituting known values, we get:

\frac{343}{0.77955} =f

f=439.9974344

The pitch that's the closest to this value is Pitch A.
