X-rays are pairt o the electromagnetic spectrum, wi wavelengths shorter nor veesible licht. Different applications uise different pairts o the X-ray spectrum.

X-radiation (componed o X-rays) is a form o electromagnetic radiation. Maist X-rays hae a wavelength in the range o 0.01 tae 10 nanometers, correspondin tae frequencies in the range 30 petahertz tae 30 exahertz (3×1016 Hz tae 3×1019 Hz) an energies in the range 100 eV tae 100 keV. However, much heicher-energy X-rays can be generatit for medical an industrial uises, for example radiotherapy, which utilizes linear accelerators tae generate X-rays in the ranges o 6–20 MeV. X-ray wavelengths are shorter nor those o UV rays an typically langer nor those o gamma rays. In mony languages, X-radiation is referred tae wi terms meanin Röntgen radiation, efter Wilhelm Röntgen,[1] who is uisually creditit as its discoverer, an who haed named it X-radiation tae signify an unkent type o radiation.[2] Spellin o X-ray(s) in the Inglis leid includes the variants x-ray(s), xray(s) an X ray(s).[3]
