In what year were x-rays discovered?

• A. 1898
• B. 1895
• C. 1901
• D. 1904

Answer: (B)

The event being tested is when X-rays were first identified as a new kind of radiation. Wilhelm Conrad Röntgen discovered them in 1895 while experimenting with a Crookes tube, observing that a fluorescent screen lit up even when not directly in the tube’s path. This prompted him to investigate and led to the first X-ray radiographs, including a famous image of a hand. Because of that foundational work, the year of discovery is 1895. Later dates are tied to milestones like the Nobel Prize awarded in 1901, or other events, but the discovery itself happened in 1895.
