In x-ray diffraction, the sample is kept in an instrument and is illuminated with x-rays. The x-ray tube and detector move in a synchronized motion, the observed signal is then recorded and studied. This phenomenon is most widely used in the determination of the distance between two consecutive atoms of an element.

19 de jul. de 2019 · Many a time you may have seen diffraction in your life but the problem is we may not notice these little things which are created due to some of the most interesting phenomena of science and diffraction is one of them.
X-ray diffraction, phenomenon in which the atoms of a crystal, by virtue of their uniform spacing, cause an interference pattern of the waves present in an incident beam of X-rays. The atomic planes of the crystal act on the X-rays in exactly the same manner as does a uniformly ruled diffraction.
Due to Huygens’s principle, we can imagine a wave front as equivalent to infinitely many point sources of waves. Thus, a wave from a slit can behave not as one wave but as an infinite number of point sources. These waves can interfere with each other, resulting in an interference pattern without the presence of a second slit. This phenomenon is called diffraction.
