Expert Answer
- In 1896, Rontgen produced cathode rays by passing electric current in electric discharge tube but when these rays stuck with the wall of the tube or anticathode, new types of rays were produced from them. These rays were called as X-rays or Rontgen rays.
- X-rays travel in a straight line like the light rays but when passed through the electromagnetic radiations, they do not get deviated.
- These rays are able to pass through the opaque substances like black paper or photographic plate.
- X-rays are used to detect a fracture in the bone, to observe defect in lungs, to diagnose cancer of oesophagus and to diagnose physical disabilities.
