👉 Radiometry is a process used to measure the temperature of an object or sample. It involves using a device that measures the light emitted by the sample and converts it into a measurable quantity, such as temperature. In other words, radiometry is a method for measuring the temperature of an object or substance in a given environment. This measurement is important in many areas of science, engineering, and medicine, where temperature is critical to understanding how substances behave under different conditions.
