The radiations emitted from hydrogen filled discharge tube show:
Correct answer: C. Line spectrum
- A. Bound spectrum
- B. Continuous spectrum
- C. Line spectrum
- D. Absorption spectrum
Explanation
A line spectrum which consists of discrete lines corresponding to single wavelength or frequency of emitted or absorbed radiation is called discrete or line spectrum.Example: Atomic spectrum such as hydrogen spectrum

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.
