- 1Emission spectrumElectrons are excited and move up energy levels
They then drop back down energy levels and release energy
Energy levels are quantized and so drops between energy levels give out specific frequencies of energy
Energy levels relate to deltaE=hv
Each set of lines relates to a drop to a different energy level
Displayed as coloured lines on black background
E.g. Lyman series for changes between energy levels for heated hydrogen
