Question
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 V is small enough so that the electrons are nonrelativistic. Ultimately, you will find the width of the central maximum for the diffraction pattern. Part A In any diffraction problem, the wavelength of the waves is important. To find the wavelength of electrons, you can use the de Broglie relation λ =, but you first must find the momentum of one of the electrons. The electrons are accelerated through a potential difference V. Use this information to find the momentum p of the electrons. Express your answer in terms of the mass of an electron me, the magnitude of the charge on an electron e, and V. ► View Available Hint(s) p= 15| ΑΣΦ Review | Constants | Periodic Table Submit ?
