X-rays are types of electromagnetic radiation probably most well-known for their ability to see through a person's skin and reveal images of the bones beneath it. Advances in technology have led to more powerful and focused X-ray beams as well as ever greater applications of these light wave...
Structure Box 1.1.1The Basic PhenomenonBefore the geometrical constraints for x-ray interference are derived the interac-tions between x-rays and matter have to be considered. There are three differenttypes of interaction in the relevant energy range. In the first, electrons may beliberated from ...
ray射线scattering基本原理raysdiffraction Diffraction effects are observed when electromagnetic radiation impinges on peri- odic structures with geometrical variations on the length scale of the wavelength of the radiation. The interatomic distances in crystals and molecules amount to 0.15–0.4 nm which corre...

x-ray A form of electromagnetic radiation with very high frequency and energy. X-rays lie between ultraviolet radiation and gamma radiation on the electromagnetic spectrum. Notes for x-ray Because x-rays can travel through solid material and affect photographic plates, they are widely used in diag...
