Question

For a face centred cubic lattice the miller indices for the first bragg's peak (smallest bragg angle) are:
(a) 002
(6) 111
(c) 001
(d) 110​

Answer 1

Answer:

c option......................

Answer 2

Answer:

The d-spacing can described as the distance between planes of atoms that give rise to diffraction peaks. Each peak in a diffractogram results from a corresponding d-spacing. The planes of atoms can be referred to a 3D coordinate system and so can be described as a direction within the crystal.
