The spectrum obtained by the radiations that emit from a hydrogen filled discharged tube is
Correct answer: A. line spectrum
- A. line spectrum
- B. band spectrum
- C. absorption spectrum
- D. continuous spectrum
Explanation
The correct answer is 'line spectrum' because the radiations emitted by a hydrogen filled discharged tube result in a series of discrete lines at specific wavelengths, known as a line spectrum. The other options are incorrect because a band spectrum consists of overlapping bands, an absorption spectrum involves absorbed wavelengths, and a continuous spectrum shows a complete range of wavelengths without distinct lines, none of which are characteristic of the radiations from a hydrogen filled discharged tube.

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.
