What else can I help you with?
What name did Marie Curie give to the process by which materials give off rays capable of fogging photographic plates?
Radioactivity
How were UV waves discovered?
Photographic plates still darkened when exposed for making spectrograms in areas beyond violet where no visible light could be seen.
Is seismology part of astronomy or chemistry?
seismology is neither a branch of astronomy nor of chemistry. It is branch of geology. and studies movements of earths plates ( Crust) and is related to study of earthquakes. Thanks, Dilip Thakur
Who made Pluto How?
Pluto was discovered by Clyde Tombaugh in 1930 at the Lowell Observatory in Arizona. Tombaugh discovered Pluto by systematically searching for unknown objects in the outer solar system using photographic plates.
What year was Pluto discovered?
Pluto was discovered in 1930 by Clyde Tombaugh.
How do x rays affect photographic plates?
X-rays will "Fog" photographic plates. That means the plates act as if 'exposed' to light. If the X-rays are intense enough, the plates will appear to be totally exposed.
what is the chemical used for making photographic plate?
For photographic plates silver halides are used.

What caused the fogging of the photographic plates that becquerel observed in 1896?
The fogging of the photographic plates that Becquerel observed in 1896 was caused by the emission of invisible, penetrating radiation from the uranium compound he was studying. This radiation interacted with the photographic plates, causing them to become fogged or exposed. This discovery ultimately led to the further investigation of radioactivity.
What does plutonium have to do with photography?
Photographic plates or films can be destroyed in direct contact with plutonium.
What is the name of a container used to store photographic plates or recording tape?
Archival box/container.
What six product groups were the main ones produced by the photographic equipment and supplies industry?
sensitized photographic film, paper, and plates; photocopy equipment; prepared photographic chemicals; still picture equipment; microfilming equipment; and motion picture equipment
What name did Marie Curie give to the process by which materials give off rays capable of fogging photographic plates?
Radioactivity
What experiments did becquerel perform?
Henri Becquerel performed experiments that involved exposing uranium salts to sunlight and observing their ability to fog photographic plates wrapped in light-proof paper. He discovered that the uranium salts emitted radiation that could penetrate opaque materials and affect photographic plates. This accidental discovery led to the development of the field of nuclear physics.
What does emulsions mean?
i think it means a suspensionof a sensitive silver salt or a mixture of silver halides in a viscous medium (as a Gelatin solution) forming a coating on photographic plates, film, or paper
How did the physicist Becquerel first observe the effect of nuclear decay?
Becquerel was conducting experiments with phosphorescent minerals. Expose them to sunlight and they glow for a while. He placed these materials on photographic plates which had heavy paper on them to stop the sunlight from penetrating and exposing the plates. He prepares some photographic plates and it was overcast for several days and he could not do the experiment. He placed the plates in a desk drawer the first day and after several days of bad weather, decided to develop the plates anyway. They had been exposed. He looked in the drawer and it contained some ore samples containing uranium. The radioactive decay of the uranium had penetrated the paper coverings and had exposed the plates.
