Question

If a plane cuts the x, y and z axes at -4, 8 and -4 what is the Miller index of the plane?

Answer 1

To determine the Miller index. you need to:

• Take reciprocals: 1/(-4), 1/8, 1/(-4)
• Clear fractions (multiply by 8): -2, 1, -2
• Reduce to lowest terms (already done)

The miller index is

$$(-2,1,-2).$$
