X-rays are electromagnetic radiations, similar to radio waves, ultraviolet rays, light rays, etc. X-rays were discovered by Roentgen, a German professor in 1895. Roentgen won Nobel Prize in Physics for this discovery. He observed that these radiations could pass through soft tissue but not through bone and other objects which would cause shadow images to be made on photographic plates. This discovery was a boon to the field of medicine. Today, X-rays help detect any defect in bones and related ligaments. It is quick, painless and safe method of examining internal organs.
