With which material is a photographic film strip coated on one side of photographic film in optical recording of sound? Correct Answer Silver halide crystals

Photographic film is a strip or sheet of transparent plastic film base coated on one side with gelatin emulsion containing microscopically small light sensitive silver halide crystals. The size and other characteristics of the crystals are determined by sensitivity, contrast and resolution of the film.
