Radiometry deals with the measurement and study of electromagnetic radiation, specifically focusing on the properties and behavior of light. It involves quantifying various radiometric quantities associated with the optical portion of electromagnetic radiation, which is further divided into ultraviolet, visible, and infrared.

Radiometry is important because it provides quantitative information about light and its interaction with matter. By accurately measuring these radiometric quantities, scientists can understand the physical characteristics and behaviors of light in different environments.

Radiometric Quantities

Radiometric quantities play a crucial role in accurately quantifying and analyzing various forms of radiant energy. The table below discusses these quantities.
