How does absorption spectrum takes place

An absorption spectrum is a spectrum of absorption lines or bands, produced when light from a hot source, itself producing a continuous spectrum, passes through a cooler gas. A material's absorption spectrum shows the fraction of incident electromagnetic radiationabsorbed by the material over a range of frequencies. An absorption spectrum is, in a sense, the opposite of an emission spectrum

Every chemical element has absorption lines at several particular wavelengths corresponding to the differences between the energy levels of its orbitals. For example, an object that absorbs blue, green and yellow light will appear red when viewed under white light. Absorption spectra can therefore be used to identify elements present in a gas or liquid. This method is used in deducing the presence of elements in stars and other gaseous objects which cannot be measured directly.
