    Answer:

    70 m.

    Explanation:

    Given,

    Frequency, f = 20 HZ

    speed of sound, v = 1400 m/s

    wavelength of the waves = ?

    we know,

    v = f λ

    [tex]\lambda= \dfrac{v}{f}[/tex]

    [tex]\lambda= \dfrac{1400}{20}[/tex]

    [tex]\lambda=70\ m[/tex]

    Hence, the wavelength of the wave is equal to 70 m.
