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 ain any diffraction problem, the wavelength of the waves is important. to find the wavelength of electrons, you can use the de broglie relation λ=hp, 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. p = (2emev)^.5part bwhat is the wavelength λ 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.
