What did Henri becquerel discover about radiation emitted from uranium salts?
Henri Becquerel discovered that uranium salts emit a form of radiation that can penetrate opaque objects and fog photographic film. This phenomenon led to the discovery of radioactivity.
What observation did Becquerel to pose another question?
Henri Becquerel observed that uranium salts emitted radiation that could expose photographic film wrapped in thick paper. This led him to question whether the radiation was related to the element's atomic structure or another property of uranium.
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.
Why are the lights turned off in making a photographic film?
Lights are turned off during the photographic film developing process to prevent exposure to light, which can interfere with the development of the film. Light can cause premature exposure of the photosensitive chemicals on the film, leading to unwanted effects or ruining the final image.
What device uses lenses to focus light rays and record an image of an object on photographic film?
A camera uses lenses to focus light rays and record an image of an object on photographic film.

How do minerals containing uranium darken photographic film?
Uranium minerals emit radiation that causes silver halide crystals in photographic film to undergo a process known as fogging. This fogging results in darkening of the film, affecting the quality of images produced.
What did Henri becquerel discover about uranium?
Antoine Henri Becquerel discovered in 1896 the natural radioactivity of uranium. The emitted radiations have effect on a photographic plate, the emulsion was decomposed under the uranium sample.
What is the collective noun for photographic films?
There is no specific collective noun form photographic film, in which case a noun suitable for the context is used, for example a roll of photographic film, a case of photographic film, an archive of photographic film, etc.
What is the collective noun for film?
There is no standard collective noun for photographic film, in which case, a noun suitable for the situation is used; for example, a case of photographic film, a cache of photographic film, a supply of photographic film, etc.

What is the duration of Photographic Memory film?
The duration of Photographic Memory - film - is 1.4 hours.
What did henri becquerel contribute to the atomic theory?
Henri Becquerel discovered radioactivity in 1896, which was a significant contribution to the atomic theory by demonstrating that atoms could spontaneously change and emit radiation. This discovery paved the way for further research into the structure of the atom and the development of nuclear physics.
When was Photographic Memory - film - created?
Photographic Memory - film - was created on 2011-09-01.
What is used to make photographic film?
Photographic film was invented in 1889 by George Eastman. Photographic film and paper is made using silver nitrate which is light sensitive.
How was radioactivity discovered?
Radioactivity was discovered on March 1, 1896, by a French physicist named Henri Becquerel, this discovery is now known as one of the most famous accidental discoveries in the history of physics. Becquerel was then awarded half of the noble prize for physics in 1903, the other half being given to Pierre and Marie Curie for their study of the Becquerel radiation.
