1. The problem statement, all variables and given/known data A simple cubic crystal with lattice parameter 0.5 nm has a plane which intersects atoms at the points (-0.5,-0.5,0), (1,-0.5,0.5) and (1,2.5,-1.5), where the coordinates have units of nm. What are the miller indices of the plane? Having read the relevant chapters of three different books I am still none the wiser, and have been unable to find a similar solution to this problem. I am truly stuck and have no idea how to begin this question; I'm hoping someone can guide me through the process to a solution.
