Physics - Emission spectra

Emission spectra

When an atom is excited, for example by heating, electrons jump from
ground state to a higher energy level. They then 'fall back' to a lower
energy level and, in doing so, emit a photon [1]or photons - they could
move back down in several steps. Again, the energy of each emitted photon
is the difference in the energy levels. If light from the substance is
spread into a spectrum, [2]there will be a series of bright lines.
