: an electromagnetic spectrum in which a decrease in intensity of radiation at specific wavelengths or ranges of wavelengths characteristic of an absorbing substance is manifested especially as a pattern of dark lines or bands.
An absorption spectrum occurs when light passes through a cold, dilute gas and atoms in the gas absorb at characteristic frequencies; since the re-emitted light is unlikely to be emitted in the same direction as the absorbed photon, this gives rise to dark lines (absence of light) in the spectrum
Absorption spectrum occurs when the light passes through a cold,dilute gas and atoms in the gas absorb at characteristic frequencies and re-emits. Showing dark lines or bands due to absorption at specific wavelengths.
