WebIf all the seven colors are present with no gaps between them, it makes a continuous spectrum. Line spectrum on the other hand only contains a few lines (wavelengths). It is important to understand the whole context of electromagnetic spectra, absorption spectra and emission spectra. Webspectrum? a. looking through the cloud with the light bulb along our sight line b. looking through the edge of the cloud with the light bulb not along our sight line c. along all lines of sight through the cloud d. both a and b e. none of the above 10. An astronomer looks at a the spectrum of a distant source. She sees only very bright lines.
