Friedrich Paschen

Friedrich Paschen was a German physicist known for his work in spectroscopy, particularly the study of atomic spectra. In the context of hyperfine structure, which describes tiny energy level differences in atoms due to nuclear spin effects, Paschen contributed to our understanding of how these differences influence spectral lines. His research helped clarify how light interacts with atoms, revealing more about the internal structures of atoms and the forces at play. This knowledge is crucial for fields like quantum mechanics and atomic physics, enhancing our understanding of the universe at a fundamental level.
