Spectrophotometry

Spectrophotometry is a technique used to measure how much light a substance absorbs at different wavelengths. It involves shining light through a sample and detecting how much light passes through compared to how much was initially emitted. The results help identify the substance and its concentration, as different materials absorb light differently. This method is widely used in chemistry, biology, and environmental science to analyze liquids and solids, making it crucial for tasks like testing water quality, analyzing food, and conducting research in laboratories.
