The atomic spectra deal with the measurement of:
Correct answer: D. All of these options
- A. Wavelengths
- B. Intensities of electromagnetic radiations emitted by atoms
- C. Intensities of electromagnetic radiations absorbed by atoms
- D. All of these options
- E. Both B and C
Explanation
Atomic spectra have different energy levels and electrons jump from one energy level to the other emitting and absorbing electromagnetic radiations. The best option is D.

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.
