Sensitivity of silver bromide to light is related to which use?
Answer and explanation
Correct answer: Photography
Silver bromide is a photosensitive salt, so it undergoes a chemical change when exposed to light. In photographic film, this light-induced decomposition helps record an image; the exposed portions later produce metallic silver during development. Therefore, photography is the correct use. Galvanisation protects iron with zinc, water purification removes impurities, and melting metals involves heating rather than photochemical change.
