    Answer:

    Wavelength of sound wave = 1 m

    Explanation:

    Given

    speed of sound wave = 340 ms^{-1}

    frequency of sound wave = 340 Hz = 340 s^{-1}

    wavelength of sound wave = ?

    We know that for all waves, the relationship between wavelength λ, frequency f and speed v is same and given by the equation:

    v = fλ

    Hence wavelength of sound wave λ = v/f

                                                                 =  340 ms^{-1} / 340 s^{-1}

                                                                 = 1 m
