    The correct answer for the question that is being presented above is this one: "B. 13m."

    The formula of wave velocity is this:

    wave velocity = f * λ

    λ = v / f

    λ = 343m/s / 26Hz

    λ = 13.20m ... ans (b)

    Here are the following choices:

    A. 5m

    B. 13m

    C. 28m

    D. 58m
