Form of short-wavelength electromagnetic radiation

X-ray radiation (also spelled in English as X-ray(s), x-ray(s), xray(s), X ray(s),[1] or, much less commonly, X-radiation) is a high-energy electromagnetic radiation. In many languages, it is referred to as Röntgen radiation, after the German scientist Wilhelm Conrad Röntgen, who discovered it in 1895[2] and named it X-radiation to signify an unknown type of radiation.[3]

X-ray wavelengths are shorter than those of UV rays and longer than those of gamma rays. There is no universally accepted, strict definition of the bounds of the X-ray band. Roughly, X-rays have a wavelength ranging from 1...
