1.5: The Rydberg Formula and the Hydrogen Atomic Spectrum
Solution: We can use the Rydberg equation (Equation 1.5.2) to calculate the wavelength: 1 λ = RH( 1 n2 1 − 1 n2 2) A For the Lyman series, n1 = 1. 1 λ = RH( 1 n2 1 − 1 n2 2) = 1.097 × 107m − 1(1 1 − 1 4) = 8.228 × 106 m − 1. Spectroscopists often talk about energy and frequency as equivalent.
