The sun spectra also have dark lines in a pattern that corresponds to the:
Correct answer: A. Absorption
- A. Absorption
- B. Emission
- C. Release
- D. Free particle
Explanation
OPTION A: The spectrum produced from the radiations from which the rays of a particular wavelength are absorbed after passing through the absorbing substance. The spectrum obtained consists of a series of dark lines in a bright background, which is called the absorption spectrum. So Spectrum of sunlight is an example of the Line absorption spectrum. Hence, A is the correct option.OPTION B: The line spectrum produced from the radiations emitted by a substance is called the emission spectrum. The spectrum of emitted radiations produces bright lines with a dark background.OPTION C: IncorrectOPTION D: Incorrect

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.
