GENERAL KNOWLEDGE

Detailed explanation-1: -A spectrograph-sometimes called a spectroscope or spectrometer-breaks the light from a single material into its component colors the way a prism splits white light into a rainbow. It records this spectrum, which allows scientists to analyze the light and discover properties of the material interacting with it.

Detailed explanation-2: -Spectroscopy can be very useful in helping scientists understand how an object like a black hole, neutron star, or active galaxy produces light, how fast it is moving, and what elements it is composed of. Spectra can be produced for any energy of light, from low-energy radio waves to very high-energy gamma rays.

Detailed explanation-3: -A spectrometer is an tool commonly used by astronomers which splits the light collected by a telescope into its colors. This allows astronomers see the details in the light from space. Astronomers know how to get a lot of special information about a space object by studying its light.
