E. None of above

Check Answer

The correct answer is A) Wilhelm Conrad Roentgen.

X-rays were discovered by Wilhelm Conrad Roentgen. In 1895, Wilhelm Conrad Roentgen, a German physicist, discovered X-rays while experimenting with cathode rays in a vacuum tube. Roentgen observed that a fluorescent screen in the room began to glow, even though it was not connected to the vacuum tube. He realized that a new kind of ray was being emitted from the tube, which he called X-rays, because their nature was unknown.

Roentgen’s discovery was groundbreaking because it marked the beginning of the field of diagnostic radiology, the use of X-rays to examine the inside of the human body. He received the Nobel Prize in Physics in 1901 for his discovery of X-rays.
