Why was Benri Becquerel interested in phosphorescence?
Becquerel was interested in phosphorescence because it involves materials that emit light after being exposed to a source of energy, such as sunlight or electricity. He wanted to better understand this phenomenon and its underlying mechanisms, which ultimately led to his discovery of radioactivity.
What was Henri Becquerel studying when he discovered radioactivity?
Henri Becquerel was studying the phenomenon of phosphorescence when he discovered radioactivity. He accidentally found that uranium salts emitted radiation that fogged photographic plates wrapped in opaque paper, leading to the groundbreaking discovery of radioactivity in 1896.
What was Henri becquerel studying when he accidentally discovered radioactivity?
Henri Becquerel was studying the phenomenon of phosphorescence when he accidentally discovered radioactivity in 1896. He found that uranium salts emitted radiation that could fog photographic plates wrapped in black paper. This serendipitous discovery laid the foundation for the field of nuclear physics.
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.
Phosphorescence is similar to what other source of light?
Phosphorescence is similar to fluorescence in that both involve emission of light by materials after they have absorbed energy. The main difference is the time scale: fluorescence is immediate, while phosphorescence has a delay before light is emitted.

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?
Henry Becquerel did not invent anything; he discovered radioactivity in 1896. This groundbreaking discovery paved the way for further research into nuclear physics and its applications in various fields. Henri Becquerel was awarded the Nobel Prize in Physics in 1903 along with Marie and Pierre Curie for their work on radioactivity.
