X-ray was discovered in 1895 by German physicist (Roentgen) and was so named because their nature was unknown at the time.
Unlike ordinary light, these rays were invisible, but they traveled in straight lines and affected photographic film.
in the same way as light. On the other hand, they were much more penetrating than light and could easily pass through the human body, wood, quite thick pieces of metal and other opaque objects.
X-ray is a form of radiant energy, like light or radio waves. Unlike lights, x-ray can penetrate the body which allows a radiologist to produce picture of internal structures.
As other medical procedures, X-ray is safe in care usage.
