Answer 1

hello mate!!

Atomic spectroscopy is the study of the electromagnetic radiation absorbed and emitted by atoms. Since unique elements have characteristic (signature) spectra, atomic spectroscopy, specifically the electromagnetic spectrum or mass spectrum, is applied for determination of elemental compositions. It can be divided by atomization source or by the type of spectroscopy used. In the latter case, the main division is between optical and mass spectrometry. Mass spectrometry generally gives significantly better analytical performance, but is also significantly more complex. This complexity translates into higher purchase costs, higher operational costs, more operator training, and a greater number of components that can potentially fail. Because optical spectroscopy is often less expensive and has performance adequate for many tasks, it is far more common[citation needed] Atomic absorption spectrometers are one of the most commonly sold and used analytical devices.

Answer 2

$\LARGE\bold\green{Atomic \: spectra}$

Atomic spectrum - (physics) a spectrum of radiation caused by electron transitions within an atom; the series of spectrum lines is characteristic of the element

Natural philosophy, physics - the science of matter and energy and their interactions; "his favorite subject was physics"

Spectrum - an ordered array of the components of an emission or wave

Fine structure - the presence of groups of closely spaced spectrum lines observed in the atomic spectrum of certain elements; "the fine structure results from slightly different energy levels"

Types of Atomic Spectrum :–

(1) Emission spectrum:

Spectrum produced by the emitted radiation is known as emission spectrum. This spectrum corresponds to the radiation emitted (energy evolved) when an excited electron returns back to the ground state.

(i) Continuous spectrum:

When sunlight is passed through a prism, it gets dispersed into continuous bands of different colours. If the light of an incandescent object resolved through prism or spectroscope, it also gives continuous spectrum of colors.

(ii) Line spectrum:

If the radiation’s obtained by the excitation of a substance are analyzed with help of a spectroscope a series of thin bright lines of specific colors are obtained. There is dark space in between two consecutive lines. This type of spectrum is called line spectrum or atomic spectrum..
