Question

If Weiss indices are 1:2:00 then miller indices are
...
a. 1:2:00
b. 1:2:0
c. 1:2:1
d. 2:1:0​

Answer 1

If Weiss indices are 1:2:00 then Miller indices are -

d) 2:1:0

• Miller indices are group of three numbers that indicates the orientation of a plane or set of parallel planes of atoms in a crystal .

• Whereas Weiss indices , give an approximate indication of a face orientation with respect to the crystallographic axes, and were used as a symbol for the face.

• Miller indices are determined by Weiss indices by first take it's reciprocal then make the fraction a whole number by multiple by suitable number.

• Weiss indices - 1:2:00

For Miller indices- 1/1 : 1/2:1/00

multiply by 2

2 : 1 : 0
