Spectral lines produced from the radiant energy emitted from excited atoms are thought to be due to the movements of electrons

Yes. Spectral lines produced from the radiant energy emitted from excited atoms are thought to be due to the movements of electrons from high energy level to low energy level of an atom.

Explanation:

There are two types of emission. (1) Emission (2) Absorption

Emission line:

When electron move from the particular high energy level to particular lower energy level with emitting a discrete wavelength radiations is known as emission spectra

Absorption Line:

When an atoms get excited by absorbing a discrete radiation with movements of electron from low energy level to high energy level produced absorption line.
