The closed packed structure have both octahedral and tetrahedral voids. In ccp structure, there is one octahedral void at the centre of body and twelve octahedral voids on the edge. Each one of which is common to four other unit cells. In ccp structure, there are eight tetrahedral voids. These voids lie on body diagonals. Two tetrahedral voids are located at each body diagonal.
The distance between an octahedral and tetrahedral void in fcc lattice would be :
A. `asqrt(3)`
B. `(asqrt(3))/(2)`
C. `(a)/(sqrt(3))`
D. `(asqrt(3))/(4)`
