Consider a section of 2-D lattice

Choose the correct statement(s) about the lattice from the following -

Answer:

A, B, D

Solution:

(a) Packing fraction of,

$η = \frac{\frac{1}{6} \times 3 \times π R ^{2}}{\frac{3}{4} \times 4 R ^{2}} = \frac{π}{3 3} = 0.91$

(b) C.N. = 6 ; it is a hexagonal 2D lattice

(c) $\frac{r}{R} = 0.155$ so, diameter $= 2 r = 0.31 R$

(d) Distance between 2 layers is $\frac{2 2}{3} R$
