Why was becquerel interested in phosphorescence?
because he works as a photographer... <3
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.
What did Henri becquerel discover accidentlly?
Henri Becquerel discovered radioactivity, together with the famous Marie Curie. The word "Becquerel" is now used as an S.I. unit of radioactivity. 1 Becquerel (Bq) means that 1 nucleus decays each second.
Phosphorescence is similar to what other source of light?
fluorescent.
If you were Becquerel what are some possible tests that you can do to identify the radiation emitted by uranium salt?
In the time of Becquerel only the photographic plate.

Radioactivity was discovered by?
Henri Becquerel shared a Nobel award in 1903 with Marie and Pierre Curie for the discovery of spontaneous nuclear radiation through experiments in 1896 involving the phosphorescence of Uranium Salts; specifically, potassium uranyl sulfate.

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.
How did Antoine Becquerel improve the atomic theory?
=Becquerel's earliest work was concerned with the plane polarization of light, with the phenomenon of phosphorescence and with the absorption of light by crystals (his doctorate thesis). He also worked on the subject of terrestrial magnetism. In 1896, his previous work was overshadowed by his discovery of the phenomenon of natural radioactivity. Following a discussion with Henri Poincaré on the radiation which had recently been discovered by Röntgen (X-rays) and which was accompanied by a type of phosphorescence in the vacuum tube, Becquerel decided to investigate whether there was any connection between X-rays and naturally occurring phosphorescence. He had inherited from his father a supply of uranium salts, which phosphoresce on exposure to light. When the salts were placed near to a photographic plate covered with opaque paper, the plate was discovered to be fogged. The phenomenon was found to be common to all the uranium salts studied and was concluded to be a property of the uranium atom. Later, Becquerel showed that the rays emitted by uranium, which for a long time were named after their discoverer, caused gases to ionize and that they differed from X-rays in that they could be deflected by electric or magnetic fields. For his discovery of spontaneous radioactivity Becquerel was awarded half of the Nobel Prize for Physics in 1903, the other half being given to Pierre and Marie Curie for their study of the Becquerel radiation
What did Henry Becquerel invent?
Henri Becquerel accidently discovered radioactivity while conducting experiments on phosphorescence. He saw that photographic plates that were still wrapped in their black paper packaging was exposed when placed near uranium salts. Therefore, this suggested a type of radiation that can pass through solid matter. He went on the share a Nobel prize with the Curies.
What is the synonym of phosphorescence?
lightvsdark
