  8. Pure research

  9. Ultra-violet Infrared On 8th November 1895 Roentgen carried out the experiment with a charge. He covered the discharge tube completely with black paper, and light couldn't get out of the tube. Next to the building he put up a screen with a special mass that lighted up when it was illuminated. The screen lighted up, although light couldn't get out of the discharge tube through the black paper. Because of different reasons the rays couldn't be cathode rays. He took the screen and carried it to the tube. After that the light became stronger and the bones of his fingers appeared on the screen. So the rays came through the human body. Roentgen called them X-rays. The „X-rays“
