Abstract
The importance of respecting the coherent properties of X-rays in the physical interpretation of the profiles of the X-ray diffraction patterns is pointed out. Drawing the analogy between Young's experiment and two-atom X-ray scattering, the author applies the elementary theory of coherence, developed for light optics, to X-ray diffraction by a linear atomic lattice. As his considerations concerning the effect of coherence on diffraction by such a lattice are impossible to verify experimentallly, he tests their correctness by spectrographical measurements of the width of an optical grating diffraction line under different coherence and experimental conditions.
