WebOne method of interpreting x-ray diffraction is the Bragg formulation. The x-ray waves are considered as being reflected by sheets of atoms in the crystal. When a beam of monochromatic (uniform wavelength) x-rays strikes a crystal, the wavelets scattered by the atoms in each sheet combine to form a reflected wave. WebQuestion: Imagine that you used an X-ray diffractometer to examine samples of iridium metal. By interpreting the X- ray diffraction pattern from this x-ray crystallography experiment you learned that iridium has a face-centered cubic unit cell, and that the radius of iridium is 1.355 A. What is the edge length of the iridium unit cell? sathya diagnostic online reports
