How do spectral lines provide evidence for the existence of energy levels?

In: Chemistry [Edit categories]

Answer:

an emission spectrum is produced after atoms are supplied with electrical energy afterwhich they emit energies as they return to ground state after excitement. the emission spectrum is produced with coloured lines on a dark background. these lines all have different wavelengths thus different frequencies and different quantums of energy. each level has a different energy and since these lines show properties of different energies they show also that atoms have discrete energy levels.

What is energy levels?
Energy level is when particles are bonded and can only take one discrete value of energy. As opposed to classical particles which can have any energy.
