X-Rays: Seeing Inside the Human Body With Physics

  1. X-rays are high-energy light waves that can pass through soft tissues.
  2. Dense materials like bone absorb X-rays, creating contrast in images.
  3. Wilhelm Röntgen discovered X-rays in 1895, earning the first Nobel Prize in Physics.
  4. X-ray imaging quickly became a revolutionary medical diagnostic tool.
  5. X-rays reveal fractures, infections, and even lung diseases.
  6. CT scans use X-rays from many angles to build 3D images of the body.
  7. Lead aprons protect patients and doctors from unnecessary radiation exposure.
  8. Modern digital detectors reduce dose while improving image clarity.
  9. X-rays are also used in security scanners and material analysis.
  10. They showcase physics at work—turning invisible waves into life-saving insight.
