Why Do We Use Miller Bravais Indices?

by

Why Do We Use Miller Bravais Indices? Miller indices are used to specify directions and planes. These directions and planes could be in lattices or in crystals. Sometimes, like in the case of Miller-Bravais indices for hexagonal lattices and crystals, additional indices are used to highlight the symmetry of the structure. What are the Miller

How Many 111 Planes Are There In A Cubic Lattice? Three close packed directions are shown as well. These correspond to (110) directions diagonally across cube faces. There are three of these for each {111} plane. Therefore, FCC structures have twelve possible combinations of {111} and (110). How many atoms are there in 111 plane
