Johann Balmer

Definition

Johann Balmer was a Swiss mathematician and physicist best known for his work in atomic spectroscopy, particularly for formulating the Balmer series. This series describes the wavelengths of light emitted by hydrogen atoms when electrons transition from higher energy levels to the second energy level, providing critical insights into the behavior of atomic structures and their spectral lines.
