Chemistry - Complementary nature of emisssion and absorption spectra

Complementary nature of emission and absorption spectra

Each black line on an absorption spectrum occurs at a wavelength of
visible (white) light absorbed by the element involved.

When this element emits light after being excited, the emission spectrum
will show coloured lines (on a black background) at exactly the same
wavelengths at which the black lines occur on the element's absorption
spectrum.
