The Rydberg Equation's Structure
Captions available
The idea
The Rydberg equation relates hydrogen's line-spectrum wavelengths to two whole numbers marking the electron's starting and ending energy levels.
In practice
Plugging different whole-number pairs into the Rydberg equation's structure reproduces each of hydrogen's observed spectral lines in turn.
Where people slip
The Rydberg equation was found empirically, by fitting hydrogen's measured lines, years before any model explained why it worked.
