This equation is called

called Bragg angles. If waves reflected from two adjacent planes of atoms

constructively interfere, then the waves reflected from all parallel planes of atoms

in the ...

This equation is called

**Bragg's Law**. The angles 0 which satisfy this equation arecalled Bragg angles. If waves reflected from two adjacent planes of atoms

constructively interfere, then the waves reflected from all parallel planes of atoms

Actually, atoms are not "points" but have spatial dimensions. Each part of the

atom scatters x rays differently. To see how

realistic picture, we must use the concept of primitive unit cell discussed in

Chapter 1.

If we had used this distance in

angles 0 = 22° and 47°. Thus, the Bragg reflections observed at 0 = 11°, 34°, and

70° would not have been predicted. Problem 2-12. What is the Bravais lattice of ...
