What caused the fogging of the photographic plates that becquerel observed in 1896?
The fogging of the photographic plates that Becquerel observed in 1896 was caused by the emission of invisible, penetrating radiation from the uranium compound he was studying. This radiation interacted with the photographic plates, causing them to become fogged or exposed. This discovery ultimately led to the further investigation of radioactivity.

How would you describe bequerel's experiments?
Henry Becquerel radioactivity experiment is an example of finding some thing out of surprise without looking for it. The actual experiment is mentioned on the wikipedia page of Henry Becquerel. Once in my Nuclear Engineering class my teacher told that Henry placed his personal belongings into a drawer along with a salt piece of Uranium and photographic plates. The plates got fogged. Henry was curious to know what caused the fogging of the plates. He experimented by placing the things that were present in the drawer earlier one by one along with a photo graphic plate and recorded the results. Well the realted link will take you to a video on the experiment conducted by Henry Becquerel.
What name did Marie Curie give to the process by which materials give off rays capable of fogging photographic plates?
Radioactivity
How did Becquerel discovered radioactivity discovered radioactivity?
Henri Becquerel discovered radioactivity in 1896 while conducting experiments with uranium salts. He accidentally found that photographic plates wrapped in black paper near a sample of uranium salts became fogged, indicating the emission of radiation from the uranium. This unexpected discovery led to further research and the development of the concept of radioactivity.
How did Henri becquerel discover radioactivity?
In 1896, while investigating phosphorescence in uranium salts, Becquerel accidentally discovered radioactivity. Investigating the work of Wilhelm Conrad Röntgen, Becquerel wrapped a fluorescent substance, potassium uranyl sulfate, in photographic plates and black material in preparation for an experiment requiring bright sunlight. However, prior to actually performing the experiment, Becquerel found that the photographic plates were fully exposed. This discovery led Becquerel to investigate the spontaneous emission of nuclear radiation.
Why did becquerel leave his crystals in the sunlight for several hours?
Becquerel left his crystals in the sunlight to study the phenomenon of fluorescence. He discovered that the uranium crystals emitted radiation that fogged photographic plates, leading to the discovery of radioactivity.
What experiments did becquerel perform?
Henri Becquerel performed experiments that involved exposing uranium salts to sunlight and observing their ability to fog photographic plates wrapped in light-proof paper. He discovered that the uranium salts emitted radiation that could penetrate opaque materials and affect photographic plates. This accidental discovery led to the development of the field of nuclear physics.
What observation caused becquerel to opose another question?
When Henri Becquerel discovered that uranium salts could produce images on photographic plates without exposure to light, he began questioning if the radiation emitted by uranium could be responsible for this effect. This observation led him to further investigate the properties of uranium and its ability to emit radiation.
How was radioactive decay first evident?
Henri Becquerel discovered it by accident when some photographic plates were left several days in a drawer with some ore samples containing uranium. The plates were not exposed to light, but when developed, the plates showed they had been exposed to something. More experimentation by Becquerel showed that this was radioactice decay of the uranium.
WHO DISCOVered radioactivity in 1896?
Radioactivity was discovered in 1896 by Henri Becquerel, a French scientist, while testing phosphorescent materials with photographic plates. He discovered that, when the plates were covered with black paper, that phosphorescent materials did not affect the plates until he used uranium salts.
Who invented natural radioactivity?
Henri Becquerel discovered natural radioactivity in 1896, when he observed that uranium salts emitted rays that could fog photographic plates. This led to further research on radioactivity by Becquerel, Marie Curie, and Pierre Curie.
