# Miller Indices Crystallographic Planes Question

• toffeefan
In summary, Miller Indices are a notation system used in crystallography to describe the orientation of crystal planes within a crystal lattice. They are determined by finding the intercepts of a plane on the three axes of the lattice and taking their reciprocals. These indices represent the orientation of a crystal plane and are used to determine crystal symmetry and predict physical and chemical properties. Their significance lies in their crucial role in identifying and understanding the properties of crystals for various applications.

Suppose i have a plane in a cubic cell that cut across the following intercepts: x=-1, y= -5/12 z=parallel. What is the miller indices of a triangular plane located at the top left corner of this rectangular plane?

Can anyone explain how to solve this? answer is not important.

The question does not make sense, or is very poorly worded. And planes do not have corners.

Furthermore, questions of this kind belong in the Homework & Coursework section of the forum, and help is only provided after the OP shows some effort towards solving the problem.

## 1. What are Miller Indices in crystallography?

Miller Indices are a notation system used to describe the orientation of crystal planes in a crystal lattice. They are represented by three numbers (hkl) and are used to identify specific crystal planes and their orientations within a crystal structure.

## 2. How are Miller Indices determined?

Miller Indices are determined by finding the intercepts of a plane on the three axes of a crystal lattice, and then taking the reciprocals of these intercepts. These reciprocals are then multiplied by a common factor to simplify the indices to their smallest integer values.

## 3. What do Miller Indices (hkl) represent?

The Miller Indices (hkl) represent the orientation of a crystal plane within a crystal lattice. The index h represents the intercept on the x-axis, k represents the intercept on the y-axis, and l represents the intercept on the z-axis.

## 4. How are Miller Indices used in crystallography?

Miller Indices are used to describe the arrangement and orientation of atoms within a crystal structure. They are also used to determine crystal symmetry and to predict the physical and chemical properties of crystals.

## 5. What is the significance of Miller Indices in crystallography?

Miller Indices play a crucial role in the study of crystallography as they allow for the identification and orientation of specific crystal planes within a crystal structure. This information is important in understanding the physical and chemical properties of crystals and their potential applications in various fields such as materials science and mineralogy.
