The speed of sound in air is about 340 m/s. What is the wavelength of sound waves produced by a guitar string vibrating at 440 Hz?

The speed of sound, the frequemcy and the wavelength is related by the equation
$v=f\ast \lambda$
speed of sound is, $v=340m{s}^{-1}$
frequency is, f=440Hz
wavelength is, $\lambda =\frac{v}{f}=\frac{340}{440}=0.77m$
