when were x rays invented

X-rays were discovered on November 8, 1895, by the German physicist Wilhelm Conrad Röntgen while experimenting with cathode rays. He observed that these rays could pass through materials and produce images on a fluorescent screen, which he described as a new kind of ray. Röntgen published his findings on December 28, 1895, in a paper titled "On a New Kind of Ray" and named the radiation "X-rays" to indicate their unknown nature at the time. This discovery marked the beginning of the use of X-rays in science and medicine.
