Atomic line spectra | Early Quantum Theory

General Chemistry 1 - Atomic line spectra

Calculate the wavelength of the line in the Lyman series that results from the transition n=4 to n=1.
Is light absorbed or emitted during this process?

E4 > E1 ⇒ E = E4 – E1 = -2.1799 × 10-18142 - 1 = 2.04 x 10-18 J

E = hcλ ⇒ λ = hcE = 9.74 x 10-8 m

E4 > E1 ⇒ emission
