What is the relation between inter planar distance and cubic edge?
The interplanar distance is the distance between parallel atomic planes within a crystal lattice. It is related to the cubic edge length by the Miller indices of the planes and the crystal system. In cubic crystals, the interplanar distance can be calculated using the formula: d = a / √(h^2 + k^2 + l^2), where 'a' is the cubic edge length and (hkl) are the Miller indices of the plane.
How many indices does the Combined DNA Index System possess?
The Combined DNA Index System (CODIS) possesses 20 indices.
What are some mineralogists?
Some notable mineralogists include Johann Wolfgang von Goethe, who made contributions to mineralogy while also being a writer and statesman, and James Dwight Dana, who is known for his work on crystal structures and mineral classification. William Hallowes Miller developed the Miller indices system for crystallography and is considered a pioneer in the field of crystallography.
What are demographic indices?
population age structures, mortality rates, sex ratios, and children - women ratios(fertility)...........these all are taken as Demographic Indices. An indicator based on just two of these variables . A multivariable indicator based directly on socioeconomic data.
Use of negative indices in serial dilutions?
Negative indices are not used in serial dilutions. Serial dilutions involve diluting a substance by a specific factor in each step, such as 1:10 or 1:100. Negative indices are not a part of this process as they do not represent a valid dilution factor.
What are the Miller indices of a plane passing through the origin?
The Miller indices of a plane passing through the origin are (0,0,0).
Can you provide some example problems involving Miller indices?
Here are some example problems involving Miller indices: Determine the Miller indices for a plane that intersects the x-axis at (1,0,0), the y-axis at (0,1,0), and the z-axis at (0,0,1). Calculate the Miller indices for a plane that passes through the points (2,1,0), (0,3,1), and (-1,0,4). Find the Miller indices for a plane that intersects the x-axis at (1,0,0), the y-axis at (-1,1,0), and the z-axis at (0,0,2).
Procedure of finding miller indices of a crystal structure?
following steps one should follow to find the miller indices of a crystal plane :Determine the intercepts of the face along the crystallographic axes, in terms of unit cell dimensions.Take the reciprocalsClear fractionsReduce to lowest terms You can visualize a a plane by by miller indices by using vesta (software for windows) or by using online Miller indices visualizer by Calistry (google it)
Why you take reciprocals of intercepts for finding miller indices?
Using reciprocals spares us the complication of infinite intercepts.Formulas involving Miller indices are very similar to related formulas from analytical geometry.
What are the Miller-Bravais indices for hexagonal planes?
The Miller-Bravais indices for hexagonal planes are a set of three integers (h, k, l) that represent the orientation of a plane in a hexagonal crystal structure. These indices are used to identify and describe different planes within the hexagonal lattice.
Describe briefly miller bravais indices?
If crystal planes and directions in hexagonal system are indexed using Miller Index, then the crystallography equivalent planes have indices which appear dissimilar. To overcome this, Miller-Bravais Index is used. In short meaning: Miller-Bravais index, used to identify a plane in a hexagonal or rhombohedral structure. The four digit of Miller-Bravais indices: (hkil). The i is always the negative of the sum of h and k. The h k l is determined similar like the Miller Index system.
What is the significance of the family of planes in crystallography and how are they represented using Miller indices?
In crystallography, the family of planes refers to a group of crystal planes that share similar characteristics. These planes play a crucial role in determining the structure and properties of crystals. Miller indices are used to represent these planes in crystallography, providing a standardized way to describe their orientation and spacing within the crystal lattice. By understanding the family of planes and their Miller indices, scientists can analyze and predict the behavior of crystals in various applications.
What are the Miller indices for the hexagonal system and how are they used to describe the orientation of crystal planes in this system?
The Miller indices for the hexagonal system are a set of three integers (h, k, l) that represent the orientation of crystal planes. They are used to describe the spacing and orientation of planes within a hexagonal crystal lattice. The indices are calculated based on the intercepts of the plane with the crystallographic axes and are used to identify specific crystallographic planes within the hexagonal lattice structure.
What is the relation between inter planar distance and cubic edge?
The interplanar distance is the distance between parallel atomic planes within a crystal lattice. It is related to the cubic edge length by the Miller indices of the planes and the crystal system. In cubic crystals, the interplanar distance can be calculated using the formula: d = a / √(h^2 + k^2 + l^2), where 'a' is the cubic edge length and (hkl) are the Miller indices of the plane.
Plural of indices?
The word "indices" is already plural, so the plural form is still the same word. The singular form is "index", e.g. One index, two indices, 24 indices, 1,000 indices.
What are some common challenges encountered when working with Miller index problems in crystallography?
Some common challenges encountered when working with Miller index problems in crystallography include understanding the concept of Miller indices, correctly identifying lattice planes, dealing with complex crystal structures, and interpreting the results accurately.
Is indices singular and plural?
"indices" is plural of "index".
