Who discovered X-Rays?
A
Einstein
B
Roentgen
C
Madam Curie
D
J. J. Thomson
Explanation: 

Detailed explanation-1: -W.C. Röntgen reported the discovery of X-rays in December 1895 after seven weeks of assiduous work during which he had studied the properties of this new type of radiation able to go through screens of notable thickness. He named them X-rays to underline the fact that their nature was unknown.

Detailed explanation-2: -1895.). Therefore, the date of 28th ofDecember, 1895 was taken as the date of X-rays discovery. This paper describes the work of Wilhelm Conrad Roentgen, Nikola Tesla, Mihajlo Pupin and Maria Sklodowska-Curie about the nature of X-rays .

Detailed explanation-3: -Wilhelm Roentgen, Professor of Physics in Wurzburg, Bavaria, discovered X-rays in 1895-accidentally-while testing whether cathode rays could pass through glass.

Detailed explanation-4: -Röntgen’s discovery occurred accidentally in his Wurzburg, Germany, lab, where he was testing whether cathode rays could pass through glass when he noticed a glow coming from a nearby chemically coated screen. He dubbed the rays that caused this glow X-rays because of their unknown nature.

Detailed explanation-5: -One roentgen of X-rays may deposit anywhere from 0.01 to 0.04 Gy (1.0 to 4.0 rad) in bone depending on the beam energy. As the science of radiation dosimetry developed, it was realised that the ionising effect, and hence tissue damage, was linked to the energy absorbed, not just radiation exposure.
