    Answer:

    Wavelength = 1.36 * 10^{-34} meters

    Explanation:

    Given the following data;

    Mass = 0.113 kg

    Velocity = 43 m/s

    To find the wavelength, we would use the De Broglie’s wave equation.

    Mathematically, it is given by the formula;

    Wavelength = \frac {h}{mv}

    Where;

    h represents Planck’s constant.

    m represents the mass of the particle.

    v represents the velocity of the particle.

    We know that Planck’s constant = 6.6262 * 10^{-34} Js

    Substituting into the formula, we have;

    Wavelength = \frac {6.6262 * 10^{-34}}{0.113*43}

    Wavelength = \frac {6.6262 * 10^{-34}}{4.859}

    Wavelength = 1.36 * 10^{-34} meters
