Absorption line spectra exhibited by atoms is a result of
- change in the kinetic energy of a movimg atom
- instability of the nucleons
-
excitation of an electron in the atom
- transition of an electron from a higher to a lower energy level
The correct answer is: C
Explanation
Absorption line spectra are produced when electrons in an atom absorb specific wavelengths of light to move from a lower energy level to a higher energy level (excitation). The absorbed energy corresponds to the difference in energy between the two levels, resulting in dark lines in the spectrum at those specific wavelengths.
