Q47.An element has a face-centered cubic fcc structure with a cell edge of a. The distance between the centres of two nearest tetrahedral voids in the lattice is a 3 (1) (2) 2 2a (3) a (4) โ2a
What This Question Tests
This question requires visualizing the positions of tetrahedral voids in an FCC lattice and calculating the distance between the two nearest ones using coordinate geometry.
Concepts Tested
Formulas Used
Distance = sqrt((x2-x1)^2 + (y2-y1)^2 + (z2-z1)^2)
