+ X-Ray Diffraction 25 of 30 > A Review Constants Periodic Table Part A X-ray diffraction can be used to obtain structural information of crystalline compounds. X-ray wavelengths are about the same size as the space between atoms in solids. X-rays aimed at a crystal are diffracted by the atoms in the crystalline lattice. This results in an X-ray diffraction pattern, which can be seen on a detector placed behind the crystal. X-rays with a wavelength of 1.58 A scatter...

An x-ray beam of wavelength λ1 is incident on a crystal at an angle α1 = 40.0° with respect to the surface and undergoes first-order reflection from a set of Bragg planes. A second x-ray beam of wavelength λ2 = 80.0 pm is incident on the crystal at an angle α2 = 60.0° with respect to the surface, and undergoes second-order reflection from the same set of Bragg planes. The set of Bragg planes of interest make an angle of...
