a. The Reciprocal lattice of a simple cube of a=0.2nm is shown in the diagram. (Black colour ) The lattice cell dimension is given below .

= 2x3.14/0.2nm=3.14/10-10=3.14X1010 m-1

For a simple cubic structure the a*=b*=c*= 3.14X1010 m-1. It can be marked in the diagram such that the distance between two points is a*=b*=c*, ie The distance between 000, 100 is a*=b*=c*= 3.14X1010 m-1

is the same for (100, 200) points, or (200,300), (000,010) or (010,020) points.

b. The black bold arrows directed to the index points represent miller indices are the reciprocal ...
