There are three basic ingredients in film: silver halides (some combination of silver iodide, silver chloride and silver bromide) to make the film sensitive to light gelatin, to bond the silver halides to the backing material a backing material, which is usually a polyester film but it can be glass. (Cameras on really big telescopes used glass plates because they don't sag in the middle.)
Silver is used in film media because it tarnishes better than other materials.Tarnish is the process of oxidation, where a metal turns from some some shiny color to a darker non-shiny color.Three Examples of Tarnish:Gold: Starts a bright shiny gold color and tarnishes to a slightly darker dull gold colorCopper: Starts a bright shiny orange-gold color and tarnishes to a green patina colorSilver: Starts a bright almost white color and tarnishes to a very dark grey, almost black colorSilver provides the best tonal range, from light to dark. It can capture light from pure white to pure black (or very close).Additionally, silver tarnishes very consistently. This provides a smooth transition from light to dark on film.
The element with atomic number 47 is Silver (Ag). It is used in photographic film, as well as solar panels, water filtration, X-rays, and disinfectants.
Are we doing your homework? It's A), and it's emulsion, not emulation
it is silver
Silver is actually recovered from the spent chemicals left after the film has been processed. Silver is used in the production of film, and when the film is developed, that silver can be (and is) recovered.
The element with the atomic number 47 is silver (Ag), and it is used to make photographic film and paper. But the atomic number determined the answer, not its use.
Photographic film was invented in 1889 by George Eastman. Photographic film and paper is made using silver nitrate which is light sensitive.
Actually, it is frequently used in the production of film for photography.

It is widely used in standard film-based (pre-digital) Photography.
