When photographic film is exposed to light the salt on the film breaks down what metal is formed?

The "salt" you are referring to is actually called silver-halide and are more commonly known as "silver salts". When silver-halide crystals are exposed to light, they form a compound known as "metallic silver"

Why should you store silver bromide in brown bottles?
Silver bromide reacts chemically when exposed to light, which is why they use it to make photographic papers.
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.
What percentage of the light falling on a typical photographic plate from a telescope is actually used to record an image on this plate?
Unfortunately, photographic film is not a very efficient light detector. Only about 2% of the light striking photographic film is able to trigger the chemical reaction needed to produce an image. Thus, roughly 98% of the light falling onto photographic film is wasted.
What happens when rhodopsin in the retina of the eye is exposed to a bright light?
When Rhodopsin in the retina of the eye is exposed to a bright light, the Rhodopsin breaks down into Retinal and Opsin, allowing us to see in many different ranges of light and darkness.rhodopsin molecules break down into molecules of a colorless protein called opsin and a yellowish organic molecule called retainal synthesized from vitamin A
What happens to LSD when exposed to light?
LSD may chemically break down and become inactive when exposed to light.

silver halide

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.
When a photographic film is exposed to light then salt on the film breaks down what meatel is formed?
The short answer is silver. In black and white film and print technology, the silver halides created by exposing the film to light in the camera or on paper under an enlarger, are reduced to silver by the developer and then the remaining halides are washed from the film during the fixing process. In some color photography, ALL of the silver is washed from the film and replaced by dyes introduced during the processing.

Describe the ways in which the unprocessed photographic paper can get damaged in transit?
When undeveloped photographic media is exposed to light or radiation (x-rays included), it can be exposed. It can also be damaged by exposure to water or other liquids. Physical damage can also be done by rough transportation, like rips, tears and folds.
How were photograms invented?
A photogram is a photographic image made without a camera by placing objects directly onto the surface of a light-sensitive material such as photographic paper and then exposing it to light. In a darkroom, or a darkened room, objects are arranged on top a piece of photographic material, usually photographic paper. When the operator is satisfied with the arrangement, the photographic material is exposed with light, usually by switching on an enlarger or other artificial light source. The material is then processed, washed and dried. The usual result is a negative shadow image that shows variations in tone that depends upon the transparency of the objects used. Areas of the paper that have received no light appear white; those exposed through transparent or semi-transparent objects appear grey.

How is an x-ray film different from a photographic film?
Basically its the same stuff - but you can wrap it differently because it will never be exposed to visible light (in normal usage).
How is the timer used along side the enlarger in the darkroom?
The timer is used to set the intervals at which the light is exposed to the photographic paper. After the timer is turned on, there is a switch that sets the exposure time. This can be put into milliseconds, seconds, or minutes. Often the photographic paper is exposed for around 15 seconds, though this depends largely on the quality of the negative, style of the photographer, contrast of the print, etc.

Why are the lights turned off in making a photographic film?
That's because photographic plates are sensitive to light.
