How are absorption lines produced

WebEmission lines refer to the fact that glowing hot gas emits lines of light, whereas absorption lines refer to the tendency of cool atmospheric gas to absorb the same lines of light. When light passes through gas in the atmosphere some of the light at particular … WebAn emission line will appear in a spectrum if the source emits specific wavelengths of radiation. This emission occurs when an atom, element or molecule in an excited state returns to a configuration of lower energy. Since every atom, element and molecule has a unique set of energy levels, the emitted photon (‘packet’ of radiation) has a discrete …

Difference Between Emission And Absorption …

WebAbsorption lines are produced by atoms whose electrons absorb light at a specific wavelength, causing the electrons to move from a lower energy level to a higher one. This process removes some of the continuum … WebStellar spectra. A star’s spectrum contains information about its temperature, chemical composition, and intrinsic luminosity.Spectrograms secured with a slit spectrograph consist of a sequence of images of the slit in the light of the star at successive wavelengths.
