Atomic spectra is a _ spectra.
Correct answer: B. Discrete
- A. Continuous
- B. Discrete
- C. Both options A and B
- D. None of these options are correct
Explanation
OPTION A: Black body radiation is an example of continuous spectra. OPTION B: When an atomic gas or vapor at much less than atmospheric pressure is suitably excited usually by passing an electric current through it, the emitted radiation has a spectrum, which contain certain specific wavelength only. Such a spectrum is called atomic spectra. Atomic spectra is an example of discrete spectra or line spectra. Hence, B is the correct option. OPTION C: As only option B is correct. Hence, it is an incorrect option.OPTION D: As only option B is correct. Hence it is an incorrect option

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.
