Who discovered x-rays?

• A. Thomas Edison
• B. William Coolidge
• C. Wilhelm Conrad Roentgen
• D. Daniel David Palmer

Answer: (C)

X-rays were discovered by Wilhelm Conrad Roentgen in 1895. While experimenting with a cathode-ray tube, he observed that a fluorescent screen in his lab lit up even when the tube was shielded from normal light. This indicated a new form of penetrating radiation beyond visible light. He named these rays X, for unknown, and soon produced the first radiograph—an image of a hand—that demonstrated their ability to image internal structures like bones. This breakthrough launched diagnostic radiology and earned Roentgen the Nobel Prize in Physics in 1901. The other figures were important in related areas, but did not discover X-rays.
