Discuss the Laue method for X-ray diffraction to evaluate the crystal structure and write its advantages over the other methods.
Added by Raymond M.
Step 1
The advantage of the Laue method over other methods is that it can be used to determine the crystal structure of a wide range of materials, including materials that are difficult to crystallize using other methods. Show more…

Refer to the following: X-ray crystallography is a method of determining the arrangement of atoms within a crystal. This method has revealed the structure and functioning of many biological molecules including vitamins, drugs, proteins, and nucleic acids (including DNA). The structure of a crystal can be determined experimentally using Bragg's law: $$ n \lambda=2 d \sin \theta $$ where $\lambda$ is the wavelength of X-ray (measured in angstroms), $d$ is the distance between atomic planes (measured in angstroms), $\theta$ is the angle of reflection (in degrees), and $n$ is the order of Bragg reflection (a positive integer). Physics/Life Sciences. A diffractometer was used to make a diffraction pattern for a protein crystal from which it was determined experimentally that X-rays of wavelength 1.54 angstroms produced an angle of reflection of $45^{\circ}$ corresponding to a Bragg reflection of order $1 .$ Find the distance between atomic planes for the protein crystal to the nearest hundredth of an angstrom.
