X-radiation (composed of X-rays) is a form of electromagnetic radiation. Most X-rays have a wavelength ranging from 0.01 to 10 nanometers, corresponding to frequencies in the range 30 petahertz to 30 exahertz (3Ã1016 Hz to 3Ã1019 Hz) and energies in the range 100 eV to 100 keV. X-ray wavelengths are shorter than those of UV rays and typically longer than those of gamma rays. In many languages, X-radiation is referred to with terms meaning RÃ¶ntgen radiation, after the German scientist Wilhelm RÃ¶ntgen, who usually is credited as its discoverer, and who had named it X-radiation to signify an unknown type of radiation.
(It was named after the discoverer of X-rays.) The Sun also emits X-rays-here is what the Sun looked like in X-rays on April 27th, 2000. This image was taken by the Yokoh satellite. Many things in deep space give off X-rays.f we could see X-rays, we could see things that either emit X-rays or halt their transmission. Our eyes would be like the X-ray film used in hospitals or dentist's offices. X-ray film sees X-rays, like the ones that travel through your skin.
