Font Paragraph Styles Voice Sensitivity 5. The dispersion relation for propagating waves is the equation w = w(k) giving the angular frequency as a function of the wavenumber. A free-electron will have the energy-momentum relation E = 2m Use this relation, in conjunction with Planck's equation and De Broglie's equation, to determine the quantum mechanical dispersion relation for the wave associated with a free electron.

Learning Goal: To understand how to find the wavelength and diffraction patterns of electrons. An electron beam is incident on a single slit of width a. The electron beam was generated using a potential difference of magnitude V. After passing through the slit, the diffracted electrons are collected on a screen that is a distance L away from the slit. Assume that Vis small enough so that the electrons are nonrelativistic. Ultimately, you will find the width of the central maximum for the diffraction pattern. Part B What is the wavelength of the electron beam? Use the de Broglie relation and the momentum that you found in Part A. Express your answer in terms of h, me, e, and V. X = [5] ΑΣΦ Submit Request Answer ?
