Meaning and Origin of "X-ray"

Wilhelm Röntgen discovered X-rays in 1895 while experimenting with a cathode ray tube. He noticed a faint glow emitted from a fluorescent screen across the room, even though the tube was covered with black paper.

  • X-rays are a type of electromagnetic radiation with very short wavelengths and high energy.
  • They are produced when a beam of high-energy electrons collides with a metal target.
  • X-rays can penetrate through matter, allowing them to be used in medical imaging to visualize internal structures.

Note: The term "X-ray" is also used to refer to the medical imaging procedure that uses X-rays to create images of the body.
