Miller Index Notation

Miller Index notation is a system used in crystallography to identify and describe the orientation of planes within a crystal's structure. It uses three numbers, called indices, which are derived by intersecting a plane with the crystal's axes, then taking reciprocals of those intercepts. These numbers are written as parentheses around them, like (h k l). The Miller indices provide a standardized way to specify directions and planes in the repeating three-dimensional pattern of a crystal, facilitating Communication and analysis of its atomic arrangement.
