    Answer:

    λ = 2.5m

    Explanation:

    Given the following :

    Speed of sound (v) = 10m/s

    If 5 oscillations pass through a point in 0.5seconds;

    Time taken (period) for 1 oscillation is :

    Number of oscillations / total time taken

    5 / 0.5 = 0.25 seconds

    Wavelength, period and Velocity are related by the formula:

    v = λ / T

    λ = v * T

    λ = 10 * 0.25

    λ = 2.5 m
