Formula and explanation
Formula: (1)/(λ) = R H ( (1)/(n f²) - (1)/(n i²) ight) Applicable Conditions: Hydrogen atomic spectral lines ( n i > n f ). Explanation: λ is the wavelength of emitted or absorbed light, R H is the Rydberg constant (approximately 1.097 × 10⁷ m⁻¹ ), n i and n f are the principal quantum numbers of the initial and final states respectively.
