<prompt> Ke mang ea sibolotseng X-ray?nan  <response>: Instruction in English: Who discovered the X-ray? . Response in English: The discovery of X-rays is credited to Wilhelm Conrad Roentgen, a German physicist who made this discovery accidentally while experimenting with cathode rays in 1895. He found that a screen coated with a fluorescent material produced a bright glow when exposed to invisible rays emanating from a cathode ray tube, even when the tube was covered to block all visible light. Roentgen called these previously unknown rays X-rays, because their nature was unknown. His discovery revolutionized the fields of physics and medicine, and earned him the first Nobel Prize in Physics in 1901. . Response in Sesotho: Ho sibolloa ha X-ray ho tlotloa ka Wilhelm Conrad Roentgen, setsebi sa fisiks sa Lejeremane se ileng sa sibolla sena ka phoso ha se ntse se etsa liteko ka mahlaseli a cathode ka 1895.
