Emission line spectrum for elements
WebAn emission spectrum occurs when the atoms and molecules in a hot gas emit light at certain wavelengths, causing bright lines to appear in a spectrum. As with absorption … WebThe emission spectrum is the spectrum of radiation emitted by a substance that has absorbed energy. Atoms, molecules, and ions that have absorbed radiation are called ‘ excited ‘. The absorption spectrum is the …
