What is Spectroscopy?
Spectroscopy: /spɛkˈtrɒskəpi/: is the study of the interaction between matter and radiated energy. Historically, spectroscopy originated through the study of visible light dispersed according to its wavelength, by a prism.
How Elements are ID'd in Stars
The elements in a star are identified using the technique of
spectroscopy. The analysis of the radiation (light) coming from a star will identify the elements in that star.
Continuous Spectrum
Emission or Bright Line Spectrum
characteristic of and determined by a specific emitting substance
subjected to a specific kind of excitation.
Absorption or Dark Line Spectrum
A spectrum of electromagnetic radiation transmitted through a substance, showing dark lines or bands due to absorption of specific wavelengths.
Electromagnetic Energy
Energy propagated through free space or through a material medium in the form of electromagnetic waves. Examples include radio waves, infrared radiation, visible light, ultraviolet radiation, X rays, and gamma rays.
