November 8 is being observed as “X-Ray Day” every year. It was on this day in 1985 German engineer Wilhelm Conrad Rontgen accidentally discovered X-Rays.
While he was attempting to know whether cathode rays could pass through glass, he saw certain glow appearing on a chemically coated substance in the vicinity.
As he was uncertain about the name of such rays, he called them “X-Rays” and ever since that name has stuck. X-Rays are energy waves of electromagnetism, 1,000 times shorter than those of light.
X-Rays have found vital applications in the fields of medicine, physics and security.
