Answer :
Spectroscopy is a highly valuable method of astronomical investigation. Astronomers can determine the composition, density, and temperature of celestial bodies by interpreting the light they emit or absorb.
Emission Spectra
- Emission Nebula
- Planetary Nebula
Absorption Spectra
- Titan's Atmosphere
- Sun
Astrophysics is the science that applies the methods and principles of physics and chemistry to the study of celestial bodies and phenomena. As one of the founders of astrophysics put it, astrophysics is about ``determining the nature of celestial bodies, not where they are, not their positions and movements. β. Stars, galaxies, exoplanets, the interstellar medium, and the cosmic microwave background. Emissions from these objects are examined across all parts of the electromagnetic spectrum, and properties examined include luminosity, density, temperature, and chemical composition. Because astrophysics is such a broad subject, astrophysicists study classical mechanics, electromagnetism, statistical mechanics, thermodynamics, quantum mechanics, relativity, nuclear physics, particle physics, atomic physics, molecular It applies concepts and methods from many fields of physics, such as physics.
