Answer» Spectrum, inoptics, the arrangement according to wavelength of visible, ultraviolet, and infraredlight. An instrument designed for visual observation of spectra is called aspectroscope;an instrument that photographs or maps spectra is aspectrograph. Spectra may be classified according to the nature of their origin,i.e.,emission or absorption. Anemission spectrumconsists of all the radiations emitted by atoms or molecules, whereas in anabsorption spectrum, portions of a continuous spectrum (light containing all wavelengths) are missing because they have been absorbed by the medium through which the light has passed; the missing wavelengths appear as dark lines or gaps. |
