Xray reflection

  1. May 27, 2008 #1
    1. The problem statement, all variables and given/known data

    X-rays 1.54 angstrom reflected off copper powder
    @ 21.65º
    25.21º
    37.06º
    44.96º
    47.58º

    2. Relevant equations

    nλ = 2d sin(Θ) ; the Bragg equation

    3. The attempt at a solution

    The cubic latice is face centered at d110? 5 planes?
    I tried plotting sin(Θ) vs. n to get the slope and calculate a, but it doesn't seem right?
    How do I find the length of an edge of the unit cell and what is the cubic lattice?
