The distance between the two tetrahedral voids (along the body diagonal) in an foc lattice with edge length "a"

`(sqrt3a)/(4)`

`(sqrt3a)/(2)`

`a//2`

Text Solution

Verified by Experts

The correct Answer is:

In FCC lattice the tetrahedral voids are present at `1/4` distance in the body diagonal
`therefore` the distance b/w two tetrahedral voids is `(sqrt(3)a)/2`.
