Number of spectral lines in hydrogen atom is :
Correct answer: D. Infinite
- A. 3
- B. 6
- C. 15
- D. Infinite
Explanation
In hydrogen atom only one electron but infinite energy states so there are infinite spectral lines.

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.
