Johannes Rydberg

Johannes Rydberg was a Swedish physicist known for his work in spectroscopy, the study of the interaction between light and matter. He formulated the Rydberg formula, which predicts the wavelengths of light emitted by hydrogen atoms when their electrons move between energy levels. This formula provided a way to understand atomic spectral lines, helping to unlock the secrets of atomic structure. Rydberg's contributions laid the groundwork for quantum mechanics, enabling scientists to explore the behavior of atoms and molecules, profoundly impacting chemistry and physics. His work remains fundamental to fields like astrophysics and laser technology.
