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.
What observation caused Henri Becquerel to pose another question?
Henri Becquerel observed that uranium salts emitted radiation that could pass through opaque materials. This led him to question what process was causing this radiation to be emitted from the uranium salts.
What observation caused Becquerel to pose another question?

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.
What causes fogging of radiographs?
Fogging of radiographs can be caused by improper handling and storage of the film, light leaks in the darkroom, expired film, or exposure to heat, humidity, or radiation. It can also occur due to improper processing techniques or using the wrong chemicals during development.

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 is the photographic term for the twinkle in their subject's eye caused by a reflection?
Catchlight.
When scientist discovered radioactivity?
Radioactivity was discovered during 1896 by Henri Becquerel, who was a French scientist when he was working on phosphorescent materials. Other research was done by Becquerel, Ernest Rutherford, Paul Villard, Pierre Curie, Marie Curie, and others afterwards.
What causes fogging of radiographs?

What is the definition of texture in interior or photographic design?
Texture is a term with which many interior or photographic designers are familiar. By definition, texture is "the properties held and sensations caused by the external surface of objects received through the sense of touch."
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
Is irritation in eyes is caused by the PAN pollutant?
Yes, irritation in eyes, which is observed in periods of strong photosmog, is caused by Peroxyacetyl Nitrate (PAN).
