Greetings, iam Edward James, Have a happy day.

What Evidence Do Line Emission Spectra Provide For The Existence Of Energy Levels In Atoms? [Solved]

The fact that a line spectrum is observed - and not a continuous one - shows that only specific energy transitions are possible within an atom. This is strong evidence for the existence of energy levels. The photon of light emitted is of a particular frequency and need not be in the visible range.
