What is the Rydberg Equation?

The Rydberg equation measures the wavelength of light emitted or absorbed during an electron's transition between energy levels in a hydrogen atom.

The Rydberg Equation Formula

The formula for the Ryderg equation is:

\[ \frac{1}{\lambda} = R_H Z^2 \left( \frac{1}{n_1^2} - \frac{1}{n_2^2} \right) \]

Where:

• \( \lambda \) is the wavelength of the emitted or absorbed light (in meters).


• \( R_H \) is the Rydberg constant (\( 1.097 \times 10^7 \, \text{m}^{-1} \)).


• \( Z \) is the atomic number (1 for hydrogen, 2 for helium, etc.).


• \( n_1 \) and \( n_2 \) are the principal quantum numbers of the energy levels involved, with \( n_2 > n_1 \).
