The distance between two octhedral voids in an fcc can be (' \(a\) ' is edge of cube)
1 \(\dfrac{a}{\sqrt{2}}\)
2 a
3 \(\sqrt{3}, \dfrac{a}{\sqrt{2}}\)
4 Both (1) and (2)
Explanation:
Octehedral voids are at edge centres and body centre. Distance (i) Edge to nearest edge (centres) \(=\mathrm{a}\) (ii) Body centre to edge centre \(=\dfrac{\sqrt{2} \cdot a}{2}=\dfrac{a}{\sqrt{2}}\)
