Distance between tetrahedral and octahedral void in fcc lattice will be
(Given edge length of unit cell = a)

Options:

Answer:

Solution:

Octahedral void is found at centre of cube and edge centre while tetrahedral voids are present at 1/4th of the distance along each body diagonal.
$2 \times$ distance between tetrahedral and octahedral voids $= \frac{\sqrt{3} a}{2}$
So distance between tetrahedral and octahedral void $= \frac{\sqrt{3} a}{4}$ .
