for the following SC cube, find the miller indexes for the planes:
FAN
KFA
HAN
http://lh6.ggpht.com/_H4Iz7SmBrbk/SvhiU8OeicI/AAAAAAAAB8M/o8QPR2ht2gA/Capture.JPG
what i leared to do was find the points that the plane intercepts the x,y,z axis, i chose axes such that x+ is pointing right and y+ upwards, then i divide to get a ratio, and then ()^-1
i chose the length of a side of the cube to be "a"
FAN -> a,a,a -> 1,1,1 -> 1 1 1
KFA-> a,inf,a -> 1,inf,1 -> 1 0 1
now for the 3rd one i have found the intercept with the z axis which came out as 1.5a
HAN-> a,a,1.5a -> 1,1,1.5 -> 1 1 2/3
my question is if i am meant to do it like that or if i am meant to divide by 1.5a instead of just a
HAN-> a,a,1.5a -> 2/3,2/3,1 -> 1.5 1.5 1
up until this question i have only had whole numbers in the muiller index, so i thought another option could be
HAN-> a,a,1.5a -> 2,2,3 -> 0.5 0.5 1/3
but then i have on;y fractions,
could someone please clear this up for me, which way (if any )) is the correct way?
