Who discovered x-ray and on what date?

• A. William Conrad Roentgen
• B. Thomas Edison
• C. Godfrey Hounsfield
• D. William Crooks

Answer: (A)

Wilhelm Conrad Roentgen is the person credited with discovering X-rays. He was experimenting with cathode rays when he noticed a fluorescent screen near the tube glow even though the tube wasn’t directly visible. This led him to conclude there was a new kind of ray that could pass through matter and create images on a screen. The date most commonly cited for this breakthrough is November 8, 1895. For context, the first X-ray photograph of a human body (a hand) was taken a few weeks later, on December 22, 1895. The other names listed did not make this discovery: Edison worked on X-ray tube development and other electrical experiments, Hounsfield later invented CT scanning, and Crookes studied cathode rays prior to the X-ray discovery.
