How did Becquerel discovered radioactivity discovered radioactivity?
he noticed the first effects of radioactivity while he observed that with exposure to the sunlight the mineral gave off a penetrating energy that could expose film.
Why are the lights turned off in making a photographic film?
That's because photographic plates are sensitive to light.
Which device uses lenses to focus light rays and record an image of an object on photographic film?
This device is commonly known as a film camera.
Does a light behave primarily as a wave or as a particle when it interacts with crystals of matter in photographic film?
Yes.
What device uses lenses to focus light rays and record an image of an object on photographic film?

How do minerals containing uranium darken photographic film?
Emitting alpha particles and gamma rays. These rays affect the photographic emulsion. The natural radioactivity of uranium was discovered by Henri Becquerel in 1896.
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 did Henri becquerel discover about uranium?

What did henri becquerel contribute to the atomic theory?
This was not what Henri Bacquerel was famous for. He was a physics lecturer and carried out various experiments. His most famous discovery was by chance leaving some Uranium salts next to a photographic film. This exposed them and turned them white. This led him to realise that some substances gave off nuclear radiation.

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.
When will digital photographic technology ever surpass the quality of the photographic film emulsion?
I think it was first done in 2006. The question would be more accurate changed from "when will" to "when did" and removing the ever. = When did digital photographic technology surpass the quality of photographic film emulsion? =
