Spectral line
Lesson Flashcards: Emission and Absorption Spectra Physics • 10th Grade
A bright or dark sharp line in a spectrum of light
Absorption line
A dark sharp line in a spectrum produced by the absorption of photons as electrons transition between certain energy levels
Emission line
A bright sharp line in a spectrum produced by the emission of photons as electrons transition between certain energy levels
Continuous spectrum
A spectrum of light with no features
Absorption spectrum
The spectrum of light produced if white light is passed through a cool material, allowing some of the light to be absorbed by electrons in the material as they transition to higher states
Emission spectrum
The spectrum of light produced by a material as the electrons in the material transition from higher to lower states, releasing photons
