How crystallographic planes are determined?
1.
Find the intercepts, r and s, of the plane with any two of the basal plane axes (a1, a2, or a3), as well as the intercept, t, with the c axes. 2.
Get reciprocals 1/r, 1/s, and 1/t..
What are the lattice planes in crystallography?
Equivalently, a lattice plane is a plane whose intersections with the lattice (or any crystalline structure of that lattice) are periodic (i.e. are described by 2d Bravais lattices).
A family of lattice planes is a collection of equally spaced parallel lattice planes that, taken together, intersect all lattice points..
What do you mean by crystallographic?
crystallography, branch of science that deals with discerning the arrangement and bonding of atoms in crystalline solids and with the geometric structure of crystal lattices.
Classically, the optical properties of crystals were of value in mineralogy and chemistry for the identification of substances..
What is a crystallography plane?
Crystal planes are defined as some imaginary planes inside a crystal in which large concentration of atoms are present.
Inside the crystal, there exists certain directions along which large concentration of atoms exists.
These directions are called crystal directions..
What is the formula for a crystallographic plane?
Recall from your multi-variable or vector calculus class that the equation of a plane can be written as a−→x + b−→y + c−→z = d, where the vector [abc] is perpendicular to the plane.
In our case, a crystallographic plane can be written as h−→a + k −→ b + l−→c = d.Dec 13, 2015.

What is the set of planes in a crystal?
A set of such planes consists of parallel evenly spaced planes which are extended to exactly fill the entire crystal; each plane is an equal distance, d (the inter-planar spacing), from its neighbouring plane..
- Crystal faces develop along planes defined by the points in the lattice.
In other words, all crystal faces must intersect atoms or molecules that make up the points.
A face is more commonly developed in a crystal if it intersects a larger number of lattice points.
This is known as the Bravais Law. - The (200) plane is located at the middle section of the FCC; it intersects with the atoms in the center of the cube's face.
In addition, the (200) plane is facing towards x-axis directions.
The (111) plane looks like a triangle with all the edges intersects to x, y, and z-axis.
