Explain line spectra and its uses.

Explanation

Line spectra (atomic spectra ) : The spectrum of the visible light are represented in the spectra . The emission spectra of atoms in the gas phase on the other hand do not show a continuous spread of identified by the appearance of bright lines in the spectra.
An emission and absorption spectrum is a photographic recording of the wavelength is called as line spectrum.

Uses : Line emission spectra are of great interest in the study of electronic structure . The characteristic of lines of the emission spectrum of the atom of a known element with the lines from an unknown When their mineraly were analysed by spectroscopic method.
