    Answer:

    Explanation:

    Given the following data;

    Mass = 9.1 X 10^{-31} kg

    Velocity = 4.8×10⁵ m/s

    Planck’s constant ( h ) = 6.6262 * 10^{-34}

    To find the wavelength;

    Applying de broglie’s equation;

    Wavelength = h/mv

    Wavelength = ) = 6.6262 * 10^{-34}/(9.1 X 10^{-31} * 4.8×10⁵)

    Wavelength = 1.52 * 10^{-71} meters
