Question

The correct unit cell dimensions for tetragonal crystal system is

• A. $a=b=c$ and $\alpha =\beta =\gamma =90^{o}$
• B. $a=b\neq c$ and $\alpha =\beta =\gamma =90^{o}$
• C. $a\neq b\neq c$ and $\alpha =\beta =\gamma =90^{o}$
• D. $a=b\neq c$ and $\alpha =\beta =90^{o},\gamma =120^{o}$

Answer 1

Answer: (B)

Tetragonal system has the unit cell dimension $a=b\neq c,\alpha =\beta =\gamma =90^\circ $ .
