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. WebWhen light passes through gas in the atmosphere some of the light at particular wavelengths is scattered resulting in darker bands. These lines came to be known as ‘spectral lines’ and were cataloged by heating common elements until they produced light and measuring …
