The speed of sound in air is approximately 340 m/s. The formula relating wavelength, frequency, and speed of sound is λ = v/f, where λ is the wavelength, v is the speed of sound, and f is the frequency. Rearranging this formula to solve for wavelength, we get λ = v/f. 
Substituting the given values, we get λ = 340/340 = 1 m. Therefore, the wavelength of the sound wave is 1 m.
