Chapter 9, Problem 18Q

Interpretation Introduction

Interpretation:

              The type of solid which give simpler X-ray diffraction pattern has to be identified and the same has to be justified.

Concept introduction:

              There are two distinct categories of solids – crystalline solids and amorphous solids. In crystalline solids, the components are neatly stacked with regular pattern repetitively in a long range order. This is the characteristic feature of crystalline solids. Amorphous solids lack such feature that the components are arranged quite randomly.

              Diffraction is a phenomenon of scattering of a beam of light into various directions from a regular array of points or planes. X-ray diffraction is an experimental method used to study the structure of crystalline solids.
