Lesson Flashcards: Emission and Absorption Spectra Physics • 10th Grade

Spectral line

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
