WebPhase problem. In physics, the phase problem is the problem of loss of information concerning the phase that can occur when making a physical measurement. The name comes from the field of X-ray crystallography, where the phase problem has to be solved for the determination of a structure from diffraction data. [1] Web4 Crystallographic planes Orientation representation (hkl)--Miller indices Parallel planes have same miller indices Determine (hkl) • A plane can not pass the chosen origin • A plane must intersect or parallel any axis • If the above is not met, translation of the plane or origin is needed • Get the intercepts a, b, c. (infinite if the plane is parallel to an
