Miller Indices for Crystal Directions and Planes

WebCrystallography: Miller Indices. Miller Indices are a symbolic vector representation for the orientation of an atomic plane in a crystal lattice and are defined as the reciprocals of the fractional intercepts which the plane makes with the crystallographic axes. The method by which indices are determined is best shown by example. WebThe crystallographic symmetries of gemstones determine their optical properties. For example, isometric crystals have crystal structures highly symmetrical in all directions. As a result of this symmetry, light traveling in any direction within an isometric crystal travels at the same speed. or543 https://gomeztaxservices.com
