How did we discover uranium?
Uranium was discovered in 1789 by Martin Klaproth, a German chemist, who isolated an oxide of uranium while analyzing pitchblende samples from the Joachimsthal silver mines in the former Kingdom of Bohemia, located in the present day Czech Republic. He named his discovery “uran” after the planet Uranus.
What was Becquerel’s theory?
He conducted an experiment on uranium salts, which he inherited from his father. He hypothesized that the uranium would absorb light and reemit it as x-rays. He put the uranium on photographic plates. He developed the plates and observed that the uranium had, in fact, emitting radiation similar to x-rays.
How did scientists come up with the idea of radio?
After the discovery of these “Hertzian waves” (it would take almost 20 years for the term “radio” to be universally adopted for this type of electromagnetic radiation) many scientists and inventors experimented with wireless transmission, some trying to develop a system of communication, some intentionally using these new Hertzian waves, some not.
Who was involved in the discovery of radioactivity?
There was a chemist and physicist named Marie Curie who made a great contribution to the discovery of Becquerel. Curie actually coined the term radioactivity. Together with Pierre, Marie’s husband, the Curies further examined Becquerel’s discovery. An extraction of uranium was done from ore.
Which is the best description of the history of radio?
History of radio. The early history of radio is the history of technology that produces and uses radio instruments that use radio waves. Within the timeline of radio, many people contributed theory and inventions in what became radio.
Who was the first person to discover radio waves?
Between 1886 and 1888 Heinrich Rudolf Hertz published the results of his experiments wherein he was able to transmit electromagnetic waves (radio waves) through the air, proving Maxwell’s electromagnetic theory. Thus, given Hertz comprehensive discoveries, radio waves were referred to as “Hertzian waves”.
