Homework Help: Miller Indices Question

  1. Sep 27, 2014 #1
    1. The problem statement, all variables and given/known data

    Question is to determine the miller indices of the plane

    2. Relevant equations

    3. The attempt at a solution

    I know how to determine miller indices but in this problem the y intercept lies outside the cube. Do I have to somehow shift it so that it lies inside the cube ?, or just leave it as is ?

    Here are the co ordinates for the intercepts (infinity, 3/2, 1)

    No, just leave it as it is. You should do only two things. 1) Inversion of the coordinates. 2) Multiplication by the LCM of the denominators.( In case a denominator is [itex]\infty[/itex], just ignore it!).
    So the miller indices are [itex] (0,2,3) [/itex].
