"Point Group" in crystallography is characterized by a set of symmetry operations such that all points in a crystal are affected by it no point in a crystal is affected by it at least one point in a crystal is affected by it at least one point in a crystal is unaffected by it What are the Miller indices of a plane that intercepts each of the crystallographic axes X, Y and Z, at 20 A? (Assume a primitive unit-cell with the dimensions a = 5 A,b =2Å and c = 4 A.) (111) (524) (425) (542)

    Q1. (D) Atleast one point in a crystal is unaffected by it Q2. (B). (524) The intercepts are 4a, 10b, 5c. To get the miller indices we have to reverse the intercept and then norma...

    point group is a group of geometric symmetries (isometries) that keep at least one point fixed. In simple words; point group is a combination of symmetry and even after application...
