Which of the following contains four Bravais lattices?
Answer & explanation
Correct answer: option 3
| Crystal system | Edge lengths | Angles | Bravais Lattices |
| Cubic | a = b = c | α = β = γ = 90° | Simple, body centred, face centred |
| Tetragonal | a = b ≠ c | α = β = γ = 90° | Simple, body centred |
| Orthorhombic | a ≠ b ≠ c | α = β = γ = 90° | Simple, body centred, face centred, end face centred |
| Monoclinic | a ≠ b ≠ c | α = γ = 90° β ≠ 90° | Simple, end face centred |
| Hexagonal | a = b ≠ c | α = β = 90° γ = 120° | Simple |
| Rhombohedral | a = b = c | α = β = γ ≠ 90° | Simple |
| Triclinic | a ≠ b ≠ c | α ≠ β ≠ γ ≠ 90° | Simple |
