X-ray
From LIMSWiki
X-radiation (composed of X-rays) is a form of electromagnetic radiation. Most X-rays have a wavelength in the range of 0.01 to 10 nanometers, corresponding to frequencies in the range 30 petahertz to 30 exahertz (3×1016 Hz to 3×1019 Hz) and energies in the range 100 eV to 100 keV. X-ray wavelengths are shorter than those of ultraviolet rays and typically longer than those of gamma rays. In many languages, X-radiation is referred to with terms meaning "Röntgen radiation," after Wilhelm Röntgen,[1] who is usually credited as its discoverer, and who had named it X-radiation to signify an unknown type of radiation.[2]
Spelling of "X-ray(s)" in the English language includes the variants x-ray(s), xray(s), and X ray(s).
