An element has a face-centred cubic (fcc) structure with a cell edge of a. The distance between the centres of two nearest tetrahedral voids in the lattice is:
A
B
a
C
D
Text Solution
Verified by ExpertsThe correct answer is:
C
In FCC, tetrahedral voids are located on the body diagonal at a distance at a distance of 
from the corner. Together they form a smaller cube of edge length 
. Therefore, distance between centres of two nearest tetrahedral voids in the lattice is also 
.
