What is emission spectra? Give their types

What is absorption spectra? Give their types.

In the following figure, one of the spectra is emission spectra and other is absorption spectra of the same element. Identify which is which?

What is an atomic spectra ?

Define - Emission Spectra

The emission spectra is observed by the consequence of transition of electrons from higher energy state to ground state of He^(+) ion. Six different photons are observed during the emission spectra, then what will be the minimum wavelength during the transition?

STATEMENT-1: Line emission spectra useful in the study of atomic. Structure. STATEMENT-2: Each element has a unique line emission spectrum.
