What is an X-ray?
In 1895, Wilhelm Conrad Röentgen was working in his laboratory at Würzburg University in Germany, when he observed crystals near a high-voltage cathode-ray tube beginning to glow. He concluded that a form of energy was being generated by the cathode-ray tube -which was able to penetrate the nearby paper – causing the crystals to glow. Röentgen named the unknown energy ‘X-radiation’.
