Question

Which of the following are correct axial distance and axial angles for a orthorhombic system?

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

Answer 1

The correct option is C $a\ne b\ne c,\alpha =\beta =\gamma ={90}^o$

For the orthorhombic crystal, the correct axial distance and axial angles for a orthorhombic system is $a\ne b\ne c,\alpha =\beta =\gamma ={90}^o$
