AgBr, or silver bromide, is a chemical compound made up of silver and bromine. It appears as a pale yellow solid and is primarily used in photography, particularly in traditional film. When exposed to light, AgBr undergoes a chemical change, making it sensitive to light and allowing images to be captured. In addition to photography, AgBr has applications in various fields, including medicine and electronics. It can be used in the production of certain types of sensors and as an antimicrobial agent. Its unique properties make it valuable in both scientific and industrial contexts.
