Wilhelm Conrad Rontgen tools that created the famous X-ray

Wilhelm Conrad Rontgen

November 8, 1895 X-ray again to make the experiment with the "cathode rays." Cathode rays consist of electron flow. Diprodusir flow by using high voltage between electrodes placed at each end of the glass tube where the air is almost entirely emptied. Cathode rays themselves are not specific and has stopped seeping by several centimeters of air. In this incident X-rays has been completely shut down his cathode ray tube with thick black paper, so that even electric light lit, no light can be seen from the tube. However, when X-rays turned on the electric current in the cathode ray tube, he was surprised to see that the light began to anneal on the screen that is located near the bench as stimulated by light. He put out the tube and screen (which is wrapped by a barium platino cyanide) stop light anneal. Because the cathode ray tube is fully closed, X-rays immediately aware that something invisible form of radiation that must come from the tube when the electric light turned on. Because this is a mysterious thing, he calls it visible radiation "X-rays" The "X" is a common mathematical symbol for something unknown.

Tempted by an accidental discovery, the X-ray investigations of other aside and concentrate on a review of things contained in the "X-rays" After several weeks of hard work, he found other evidence such as this: (1) X-ray beam can make various chemical objects in addition to "barium platinocyanide." (2) X-rays can break through the various objects that do not penetrate the normal light. Special X-rays found that X rays can penetrate the meat directly but stopped on his bones. By putting his hand between the cathode ray tube and the glowing screen, X-rays can see on the screen image of hand bones. (3) X-ray running vertically; not like electrically charged particles, X-ray did not terbelokkan by magnetic fields.

X-rays give a big contribution and advancement of world dentistry

Month December 1895 Rontgen wrote his first paper on X-rays Report in a short time arouse attention and uproar. Within a few months, hundreds of scientists to investigate X-rays, and within a year about 1000 papers published about it! One of the scientists who rely directly investigation of X-ray findings is Antoine Henri Becquerel. This man, although its main purpose to investigate X-rays, it is important to find the phenomenon of radioactivity.

In general, X-ray work when high energy electrons on target. X-rays themselves do not contain electrons, but electron magnetic waves. Therefore, he is basically similar to the radiation that can be seen the eye (ie light waves), except X-ray wavelengths much shorter.

The use of X-rays of the best known - of course - in the field of medical and dental diagnosis. Another use is in the field of radiotherapy, in which X-rays used to destroy malignant tumors or prevent their growth.

X-rays are also widely used in various industrial purposes. For example, can be used for measuring thickness of object or find something hidden damage. X-rays are also useful in many areas of scientific investigation, ranging from biology to astronomy. In particular, X-ray scientists presenting large amounts of information relating to atomic and molecular structure.

Nevertheless, one should not exaggerate the significance of X-ray rate. It is true, the use of X-ray brings many benefits, but one can not say he has revolutionized the whole of our technology, like Faraday's discovery of electro-magnetic proof. Similarly, one can not say the discovery of X-ray is truly a fundamental importance in the theory of science. Ultraviolet light (a wavelength shorter than visible light by the eye) has been known nearly a century earlier. The existence of X-rays - which have similarities with ultraviolet waves, but still much shorter wavelength - still within the framework of classical physics. Above all, I think the significance of X-ray proper place under the discovery Becquerel have more fundamental significance.

X-rays do not have children, so he and his wife raised the child was a girl. In 1901 Röntgen received the Nobel Prize for physics, which for the first time be given to the field. He died in Munich, Germany in 1923.
