An emission line will appear in a spectrum if the source emits specific wavelengths of radiation. This emission occurs when an atom, element or molecule in an excited state returns to a configuration of lower energy. Since every atom, element and molecule has a unique set of energy levels, the emitted photon (‘packet’ of radiation) has a discrete …
