What are Bravais Lattices?
Bravais Lattice refers to the 14 different 3-dimensional configurations into which atoms can be arranged in crystals. The smallest group of symmetrically aligned atoms which can be repeated in an array to make up the entire crystal is called a unit cell. There are several ways to describe a lattice. The most fundamental description is known as the Bravais lattice. In words, a Bravais lattice is an array of discrete points with an arrangement and orientation that look exactly the same from any of the discrete points, that is the lattice points are indistinguishable from one another. Out of 14 types of Bravais lattices some 7 types of Bravais lattices in three-dimensional space are listed in this subsection. Note that the letters a, b, and c have been used to denote the dimensions of the unit cells whereas the letters 𝛂, 𝞫, and 𝝲 denote the corresponding angles in the unit cells.
How to Calculate Interplanar Angle for Orthorhombic System?
Interplanar Angle for Orthorhombic System calculator uses Interplanar Angle = acos((((Miller Index along plane 1*Miller Index h along plane 2)/(Lattice Constant a^2))+
((Miller Index l along plane 1*Miller Index l along plane 2)/(Lattice Constant c^2))+
((Miller Index k along Plane 1*Miller Index k along Plane 2)/(Lattice Constant b^2)))/
sqrt((((Miller Index along plane 1^2)/(Lattice Constant a^2))+((Miller Index k along Plane 1^2)/(Lattice Constant b^2))*((Miller Index l along plane 1^2)/(Lattice Constant c^2)))*
(((Miller Index h along plane 2^2)/(Lattice Constant a^2))+((Miller Index k along Plane 1^2)/(Lattice Constant b^2))+((Miller Index l along plane 1^2)/(Lattice Constant c^2))))) to calculate the Interplanar Angle, The Interplanar angle for Orthorhombic system formula is defined as the angle between two planes, (h1, k1, l1) and (h2, k2, l2) in a Orthorhombic system. Interplanar Angle is denoted by θ symbol.
