This causes line emission spectra to be produced, as shown below. This is not a continuous spectrum as only light of specific frequencies and specific colours are produced. Different types of ...

The emission of radiation can be analysed by an ‘emission spectrum’. The different coloured lines show the frequencies emitted by electrons in atoms.

Colors of emission spectra are due to loosely-bound valence electrons being excited in a flame and dropping back down while emitting light. Warning! Once the flame has started, DO NOT add more ...
