The discrete spectral lines of line spectra occur when excitation of electrons takes place in
Open in App
Solution
The correct option is A Solids
In solids atoms are not movable so the energy required to knock the electrons is same, but for liquids and gases, the atoms can move with some speed, thus the electrons that knock out may or may not go to the initial orbit. Thus, for solids discrete spectral lines are observed.
