Wolfgang Fraunhofer

Wolfgang Fraunhofer was a notable German physicist and optical scientist, renowned for his pioneering work in spectroscopy—the study of how matter interacts with light. His research led to the development of precise measurement techniques that help analyze the composition of materials. These advancements are foundational in fields like chemistry, environmental monitoring, and manufacturing quality control. Fraunhofer's contributions also include the discovery of the dark absorption lines in solar spectra, known as Fraunhofer lines, which have been crucial for understanding the Sun's composition. His work has significantly influenced modern optical and measurement technologies.
