visible light spectrophotometry

Visible light spectrophotometry is a technique used to measure how much light a substance absorbs within the visible spectrum (about 400-700 nm wavelengths). When light passes through a sample, some wavelengths are absorbed while others pass through. By analyzing the amount of light absorbed at specific wavelengths, scientists can determine the concentration and properties of substances, such as dyes or biological molecules. This method is precise, quick, and widely used in fields like chemistry, biology, and environmental science to analyze samples and understand their composition.
