Materials - determining indices for planes. can someone check answers?

  1. Sep 1, 2012 #1
    1. The problem statement, all variables and given/known data
    I'm not sure if this is the right section, but I also posted in the chemistry section. I'm taking a materials engineering class which involves a lot of chemistry.

    I attached the problem.


    2. Relevant equations



    3. The attempt at a solution

    Plane A: since the plane crosses the origin, I will define the origin to be at x=+1
    x=-1 y=1/2 z=3/4
    1/x=-1 1/y=2 1/z=4/3
    →(-1 2 4/3)→(-3 6 4)

    Plane B: x=infinity y=1/4 z=infinity
    1/x=0 , 1/y=4 , 1/z=0
    →(0 4 0)=(0 1 0)

    Plane c: x=infinity y=3/2 z=1
    1/x=0 1/y=2/3 1/z=1
    →(0 2/3 1)→(0 2 3)


    I'm not sure if I did it right. Could someone please check?
