Question

what is bravais lattice?

Answer 1

The 14 Bravais lattices are grouped into seven lattice systems: triclinic, monoclinic, orthorhombic, tetragonal, rhombohedral, hexagonal and cubic. ... A crystal family is determined bylattices and point groups. It is formed by combining crystal systems which have space groups assigned to a common lattice system.

Answer 2

Answer:

(1) There are seven crystal systems according to thee edges (a, b, c) and angles (z, p, 7).

(2) The constituents of the crystal may be present at corners, face centres, body centres, edge centres and voids.

(3) By mathematical analysis, it has been proved that only fourteen different kinds of space lattices are possible.

(4) Hence there are fourteen different ways of arrange ment of the lattice basis.

(5) These fourteen lattices of seven erystal systems are called Bravais lattices.
