Who discovered the Gamma Rays?

A. Alfred Marshall
B. Paul Villard
C. Bohar
D. Jabar bin Hayan
E. None of above

Check Answer

The correct answer is B) Paul Villard.

The discovery of gamma rays is credited to Paul Villard. He was a French chemist and physicist who discovered gamma rays in 1900 while studying the radioactivity of a sample of the mineral cleveite. At the time, scientists were familiar with alpha and beta rays, but Villard discovered a new type of radiation that was more penetrating than alpha or beta rays, which he named gamma rays.

Gamma rays are a form of electromagnetic radiation and have the highest energy and shortest wavelength within the electromagnetic spectrum. They are emitted by nuclear processes and are also produced by some astronomical objects such as the sun, stars and supernovae. Gamma rays are highly ionizing and can be dangerous at high doses.
Villard’s discovery of gamma rays was an important step in the understanding of the nature of radioactive materials and the properties of electromagnetic radiation. It also opened the way for further study and research in the field of nuclear physics, radiation biology and in the field of astronomy and astrophysics.
