Answer Details
Absorption line spectra exhibited by atoms is a result of the transition of an electron from a higher to a lower energy level. When energy is absorbed by an atom, an electron moves from a lower energy level to a higher one. Conversely, when an electron moves from a higher energy level to a lower one, energy is emitted in the form of electromagnetic radiation. This radiation is observed as a spectrum of colored lines with specific wavelengths that correspond to the specific energy levels involved in the transition. The spectrum produced is unique for each atom, providing a way to identify the atoms present in a sample. Therefore, the correct option is (d) transition of an electron from a higher to a lower energy level.
