GENERAL KNOWLEDGE

Detailed explanation-1: -An absorption spectrum has dark lines or gaps in the spectrum corresponding to wavelengths that are absorbed by the gas.

Detailed explanation-2: -This is called an absorption spectrum, also known as a dark-line spectrum. The dark lines are called absorption lines. Each one of these lines represents where atoms in the solar atmosphere blocked a certain wavelength of light.

Detailed explanation-3: -When we see dark lines in a spectrum, they correspond to certain wavelengths being missing due to absorption by matter (in the form of atoms/molecules) on their way. So the dark line represents “absence of light” in a spectrum, not any particular wavelength (color) of light.
