Discovery of X-Ray Beams

Wilhelm Roentgen was already working on the effects of cathode rays during 1895, before he actually discovered X-rays.

November 8, 1895 inside a laboratory

Totally dark room Well-covered discharge tube Barium platinocyanide

Cont

Photographic plate to capture the image of various objects of random thickness placed in the path of the rays

"roentgenogram“ He declared that X-ray beams are produced by

the impact of cathode rays on material objects Scientists in many countries started to

experiment with these new rays, and progressive doctors very quickly used them as a diagnostic tool.

X-radiation (x-ray)

Extremely short wavelength and high frequency with wavelengths ranging from about 10−8 to 10−12 meter and corresponding frequencies from about 1016 to 1020 hertz (Hz).

The Nobel Prize

In 1900 Professor Roentgen accepted a position at the University of Munich.

In 1901, Roentgen received the first ever Nobel Prize in Physics.

Later

Röntgen refused to patent his discovery and gave the money that came with the Nobel Prize to his university.

Röntgen died at Munich on February 10, 1923, from carcinoma of the intestine.

In 2004, an element was named after him. Atomic Number: 111 Standard Atomic Mass: 272 u
