X-ray Diffraction.

  1. Jan 7, 2009 #1
    1. The problem statement, all variables and given/known data

    A powdered sample of a simle cubic crystal with a lattice constat of 2.83 x 10^-10 m scatters X-rays of wavelength 1.54 x 10^-10 m. What is the smallest angle of scattering that will be observed from this sample?

    2. Relevant equations

    2dsinθ = nλ

    3. The attempt at a solution

    I simply used the equation above to calculate θ, but I wasn't sure what they mean by smallest angle of scattering whats this?

    Is it 15.8 degrees?

    The smallest angle corresponds to the largest value of d.
    For cubic crystal this is d100=a.
