photometric techniques

Photometric techniques involve measuring the intensity and brightness of light emitted, reflected, or transmitted by objects. Using specialized instruments called photometers, scientists quantify light levels across different wavelengths, which helps analyze properties like color, material composition, or surface features. These measurements are essential in fields like astronomy, chemistry, and manufacturing, enabling precise assessment of how much light interacts with objects. In essence, photometry provides a standardized way to evaluate and compare the brightness and light characteristics of various sources or surfaces accurately.
