Which of the crystal systems has more than one type of Bravais lattice...
Monoclinic Crystal System:
Monoclinic crystal system is one of the seven crystal systems. It is characterized by having one crystallographic axis of unequal length compared to the other two axes, which are perpendicular to each other.
Bravais Lattices:
Bravais lattices are the 14 possible 3-dimensional lattice types which represent the geometric arrangement of the lattice points. Monoclinic crystal system has more than one type of Bravais lattices. The two types of Bravais lattices that belong to the monoclinic crystal system are:
1. Primitive Monoclinic Lattice:
- In this lattice, lattice points are only located at the corners of the unit cell.
- The lattice parameters are a, b, c (unequal) and angles α = γ = 90°, β ≠ 90°.
2. Base Centered Monoclinic Lattice:
- In this lattice, lattice points are located at the corners as well as at the center of the faces of the unit cell.
- The lattice parameters are a, b, c (unequal) and angles α = γ = 90°, β ≠ 90°.
Conclusion:
Since the monoclinic crystal system has two different types of Bravais lattices, it is the crystal system that meets the criteria of having more than one type of Bravais lattices. This distinguishes it from other crystal systems such as hexagonal, rhombohedral, and triclinic, which have only one type of Bravais lattice.
