In Figure 4.6, rays are shown scattering off atoms that are lined up in columns, with the atoms in one atomic plane exactly above those in the plane below. Actually, the atoms in different planes are usually not aligned this way. They might, for instance, be aligned as in the accompanying figure. Does this affect the validity of the Bragg law (4-1 )? Explain your answer.
