Solving a problem in physics section 20 paragraph 73 qu

73. In the face of the crystal of nickel falls parallel to the electron beam. The crystal is rotated so that the slip angle φ changes. When this angle is equal to 640, there is a maximum reflection electron diffraction peak corresponding to the first order. Taking the distance d between the atomic planes of the crystal to 200 pm, to determine the de Broglie wavelength λ of electrons and their speed υ.
