What Is Spectroscopy?

The study and analysis of light according to its component wavelengths is called Spectroscopy.

Spectroscopy requires mainly three things:

(1) a source of light,

(2) a disperser to separate the light into its different wavelength components, and

(3) a detector to sense the presence of light after dispersion.

The device used for detecting and analyzing wavelength components is called a spectrometer.

Early astronomers used spectroscopes to study the composition of planets and stars.

It also led to the discovery that the universe is expanding rapidly and isotropically.
