Answer
Wilhelm Röntgen was a German physicist who discovered X-rays. In 1895, he was studying the electrical discharge of a cathode ray tube. He noticed that a fluorescent screen across the room lit up when the tube was turned on. He realized that this was due to invisible rays being emitted from the tube, which he called "X-rays". X-rays are a type of electromagnetic radiation that can pass through matter.
