Radiometry

Radiometry is the science of measuring electromagnetic radiation, including visible light, infrared, and ultraviolet. It quantifies how much energy radiation carries and helps us understand how it interacts with materials. Key concepts include power (the total energy per second), intensity (power per unit area), and flux (total energy passing through an area). Radiometry is crucial in fields such as photography, astronomy, and environmental studies, enabling us to assess lighting conditions, energy efficiency, and the effects of radiation on the ecosystem. Through these measurements, we gain valuable insights into the behavior of light and its impact on our world.
