Definitions for "Emission spectrum"
emission spectra. Compare with absorption spectrum. A plot of relative intensity of emitted radiation as a function of wavelength or frequency.
The spectrum of bright lines against a dark background obtained when an atom or molecule emits radiation when excited by heat or an electric discharge.
a plot of emitted light wavelength versus the relative intensity of emitted light. Essentially a plot of wavelength versus the probability that the emitted light will have the energy of that wavelength.
