What is the de Broglie wavelength of electrons with the following value of kinetic energy? 1.06 keV.

    I heard you the first time.

    De Broglie wavelength is h/(momentum)

    h is Planck's cnstant

    Use the Kinetic Energy of the electron (E) to get the momentum.
    Momentum = sqrt(2E*m)

    The energy E will have to be in Joules. I trust you know how to make that conversion.
