    Answer:

    0.5 m

    Explanation:

    Given:

    Wave velocity ( v ) = 360 m / sec

    Frequency ( f ) = 720 Hz

    We have to calculate wavelength ( λ ):

    We know:

    v = λ / t [ f = 1 / t ]

    v = λ f

    = > λ = v / f

    Putting values here we get:

    = > λ = 360 / 720 m

    = > λ = 36 / 72 m

    = > λ = 0.5 m

    Hence, wavelength of sound is 0.5 m.
