Which of the following is not true about the voids formed in 3 dimensional hexagonal close packed
structure?
(1) A tetrahedral void is formed when a sphere of the second layer is present above triangular
void in the first layer.
(2) All the triangular voids are not covered by the spheres of the second layer.
(3) Tetrahedral voids are formed when the triangular voids in the second layer lie above the
triangular voids in the first layer and the·triangular shapes of these voids do not overlap.
(4) Octahedral voids are formed when the triangular voids in the second layer exactly overlap
with similar voids in the first layer.
