Wilhelm Röntgen was a German physicist born in 1845 who discovered X-rays in 1895 while experimenting with cathode ray tubes in a dark room. On November 8, 1895, he noticed fluorescent screens lighting up when placed near the tube and found they were caused by a new type of radiation which he named X-rays. He went on to use X-rays to take the first medical radiograph, known as a "roentgenogram", and scientists quickly began using the discovery for medical imaging. In 1901, Röntgen received the first Nobel Prize in Physics for his discovery of X-rays.

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.
- 5. 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).
