A spectrum that displays no energy except at very specific wavelengths where intense radiation is observed is a(n) ____ spectrum.
A) absorption
B) emission
C) continuous
D) Doppler
E) ionization

Question

Quizplus · Accepted Answer

Emission spectra are characterized by bright lines on a dark background, each line corresponding to a specific wavelength of light emitted by an atom or molecule transitioning between energy levels. This contrasts with absorption spectra, which show dark lines on a continuous spectrum, continuous spectra, which show a seamless range of colors or wavelengths, Doppler spectra, which are related to the change in frequency or wavelength of a wave in relation to an observer who is moving relative to the wave source, and ionization, which is a process that does not directly relate to the type of spectrum described.
