discovered in 1895 by Wilhelm Conrad Röntgen
X-ray is an [[electromagnetic wave]] with a wavelength of about 10<sup>-10</sup> meters, which is beyond the range of wavelength visible to the human eye. It is often used in hospitals to produce images of patient's internal organs and bones on a photographic plate.
