When was the x ray

This radiative process is similar to what happens when light is produced except that light results from atomic rather than nucleic excitations. In fact, both light and X-rays are part of the same physical phenomenon: electromagnetic radiation. X-rays can simply be thought of as high energy i.

It is because of their high energy that X-rays can penetrate through many objects. However there are differences in penetration through different materials due to the differences in the material densities. Once Roentgen decided he had proven the existence of new, invisible rays, he captured a number of X-ray images on film and sent them to various scientists and organizations to claim his stake in this discovery.

Roentgen's first experiments took place in November , the communications went out by January of , and by February of that year a number of other scientist, who possessed exactly identical equipment, were able to duplicate Roentgen's results.

Through experimentation, he found that the mysterious light would pass through most substances but leave shadows of solid objects. Roentgen quickly found that X-rays would pass through human tissue too, rendering the bones and tissue beneath visible.

News of his discovery spread worldwide, and within a year, doctors in Europe and the United States were using X-rays to locate gun shots, bone fractures, kidney stones and swallowed objects.

Honors for his work poured in--including the first Nobel Prize in physics in For the first time in 40 years, the Republican Party wins control of both the U.

John F. Kennedy, 43, becomes the youngest man ever to be elected president of the United States, narrowly beating Republican Vice President Richard Nixon. Few scientific breakthroughs have had as immediate an impact as Wilhelm Conrad Roentgen's discovery of X-rays, a momentous event that instantly revolutionized the fields of physics and medicine.

The X-ray emerged from the laboratory and into widespread use in a startlingly brief leap: within a year of Roentgen's announcement of his discovery, the application of X-rays to diagnosis and therapy was an established part of the medical profession.

Roentgen's scientific career was one beset with difficulties. As a student in Holland, he was expelled from the Utrecht Technical School for a prank committed by another student. He was particularly interested in cathode rays and in assessing their range outside of charged tubes. On November 8, , Roentgen noticed that when he shielded the tube with heavy black cardboard, the green fluorescent light caused a platinobarium screen nine feet at away to glow - too far away to be reacting to the cathode rays as he understood them.

He determined the fluorescence was caused by invisible rays originating from the Crookes tube he was using to study cathode rays later recognized as electrons , which penetrated the opaque black paper wrapped around the tube. Further experiments revealed that this new type of ray was capable of passing through most substances, including the soft tissues of the body, but left bones and metals visible. One of his earliest photographic plates from his experiments was a film of his wife Bertha's hand, with her wedding ring clearly visible.

To test his observations and enhance his scientific data, Roentgen plunged into seven weeks of meticulous planned and executed experiments.
