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? Thanks.
