    Answer:

    0.54mm

    Explanation:

    Given the following :

    Wavelength (λ) of Soundwave in air = 0.12mm

    Velocity of sound wave (v) = 340m/s

    Calculate the frequency (f) :

    v = fλ

    Wavelength to metres

    1000mm = 1 m

    0.12mm = (0.12/1000)m

    = 0.00012m

    v = fλ

    340 = F * 0.00012

    f = 340 / 0.00012

    f = 2833333.3 Hz

    Wavelength of Soundwave in the patient:

    Velocity of sound wave through body tissue = 1540m/s

    Therefore,

    Using v = fλ

    λ = v / f

    λ = 1540 / 2833333.3

    λ = 0.0005435m

    λ = (0.0005435 * 1000)mm

    λ = 0.5435mm = 0.54mm
