Crystallography: Class-09/ Module-01 (Hexagonal Vs. Trigonal system)

Описание: Concepts of Geology' is the online platform to gain and share the knowledge of Geology. Geology is the subject where we study the earth from different aspects. The subject will be covered in a sequence of comprehensive classes.
In this session concepts of geology has appeared with subbranch of geology, that is crystallography.
We were on the first module and today we will learn the relationship between hexagonal and trigonal system.
Module- 01: Distribution of atoms inside a crystal
• 1.1 The Pioneer Observations
• 1.2 Concepts of Unit Cell & Lattice
• 1.3 Choice of unit cell
• 1.4 Unit Cells On 2d: Plane Lattices
• 1.5 Unit Cells On 3d: The Basic Shapes
• 1.6 The Crystal Systems
• 1.7 Non-Primitive Unit Cells
• 1.8 The Bravais Lattices/ space lattices
• 1.9 The Trigonal crystal system
• 1.10 The shape and symmetry of the Unit Cells & mineral Crystals
