Emission spectrum :
- The spectrum produced by emitted radiation is called emission spectrum.
- The emission spectrum contains bright lines on the dark back¬ground.
- The emission spectrum corresponds the radiation emitted when an excited electron returns back to the ground state.
Absorption spectrum : - The spectrum produced by absorption of radiation is called absorption spectrum.
- The absorption spectrum contains dark lines on the bright back¬ground.
- The absorption spectrum corresponds the radiation absorbed in exciting an electron from lower to the higher energy levels.
