WebAn emission line will appear in a spectrum if the source emits specific wavelengths of radiation. This emission occurs when an atom, element or molecule in an excited state returns to a configuration of lower energy. Since every atom, element and molecule has a unique set of energy levels, the emitted photon (‘packet’ of radiation) has a discrete … WebAbsorption Spectra. An atom can be raised to an excited state by the absorption of a photon; When white light passes through a cool, low pressure gas it is found that light of … WebAn absorption line is produced when photons from a hot, broad spectrum source pass through a cooler material.

WebAbsorption lines are produced by atoms whose electrons absorb light at a specific wavelength, causing the electrons to move from a lower energy level to a higher one. This process removes some of the continuum … WebLine spectra is a phenomenon which occurs when excited atoms emit light of certain wavelengths which correspond to different colours. The emitted light can be observed as a series of coloured lines with dark spaces in between. These series of coloured lines are called line or atomic spectra.
