In hydrogen spectrum if n₁ = 6, then the spectral lines lie in:
Correct answer: D. Humphery
- A. Balmer
- B. Paschen
- C. Pfund
- D. Humphery
Explanation
The formula for spectral lines is:1/λ = RH (1/nl2 - 1/nh2)Where nl = lower orbit nh = higher orbitThe series are in the orderSeriesLymannBalmerPaschennBrackettPfundHumpherynl123456So, for nl = 6, it is Humphery's series. Given by: 1/λ = R(1/62 - 1/n2) n=7,8,9...

About Atomic Spectra
Atoms emit or absorb light at specific wavelengths because electrons occupy quantized energy levels and change levels by absorbing or releasing photons. The topic covers emission and absorption spectra, spectral series, hydrogen’s line spectrum, energy-level transitions, and the relation between wavelength, frequency and photon energy.
