Determining the distance between the planes of 1 a model crystal lattice using Bragg ’ s Law
نویسندگان
چکیده
Bragg’s Law provides a means of explanation when investigating a crystal structure by relating the space between the spheres to the scattering angles of microwaves. This lab explored the phenomenon of Bragg diffraction by looking at the distances between the planes of a three dimensional crystal lattice. Using a microwave emitter, microwave were projected onto the crystal lattice, and then a receiver measured the reflectance intensity at various angles. The actual value of the distance between the planes of the crystal lattice was found to be 0.038 ± 0.001 m; and the average of the experimental values for the distance between planes was found to be 0.0381 ± 0.0014 m.

Formation of Bragg Band Gaps in Anisotropic Phononic Crystals Analyzed With the Empty Lattice Model
Bragg band gaps of phononic crystals generally, but not always, open at Brillouin zone boundaries. The commonly accepted explanation stems from the empty lattice model: assuming a small material contrast between the constituents of the unit cell, avoided crossings in the phononic band structure appear at frequencies and wavenumbers corresponding to band intersections; for scalar waves the lowes...
متن کاملThe significance of Bragg's law in electron diffraction and microscopy, and Bragg's second law.
Bragg's second law, which deserves to be more widely known, is recounted. The significance of Bragg's law in electron diffraction and microscopy is then discussed, with particular emphasis on differences between X-ray and electron diffraction. As an example of such differences, the critical voltage effect in electron diffraction is described. It is then shown that the lattice imaging of crystal...
متن کاملForward Diffracted Parametric X Radiation From a Thick Tungsten Single Crystal at 855 MeV Electron Energy
Features of forward diffracted Parametric X-Radiation (PXR) were investigated at experiments with the 855 MeV electron beam of the Mainz Microtron MAMI employing a 410 μm thick tungsten single crystal. Virtual photons from the electron field are diffracted by the (101̄) plane at a Bragg angle of 3.977. Forward emitted radiation was analyzed at an energy of 40 keV with the (111) lattice planes of...

متن کاملNeutron diffraction from sound-excited crystals
A longitudinal sound wave modulates the regular arrangement of the atomic planes of a crystal in two ways: first, the spacing between the atomic planes is modified in the regions of compression and expansion introducing a macroscopic strain and, second, the lattice planes acquire a velocity in the oscillating strain field. Bragg reflection in a strained crystal maintains the energy of the radia...
