What is the total number of different types of unit cells in tetragonal crystal system?

Options

  1. A1
  2. B2
  3. C3
  4. D4

Correct answer

A. 1

Step-by-step solution

The tetragonal crystal system is defined by unit cell parameters where a = b c and = = = 90^ . Two Bravais lattice types exist in this system: A primitive (P) tetragonal unit cell contains lattice points only at the corners. A body-centered (I) tetragonal unit cell has points at the corners and one at the body center. This gives a total of two distinct unit cells in the tetragonal system. The correct answer is B.
