Question

how does the emission of photons at different frequencies from an atom provide evidence for discrete atomic energy levels? it shows that electrons can occupy any energy state. it indicates that electrons transition between specific energy levels, releasing specific amounts of energy. it suggests that atoms are constantly absorbing energy. it demonstrates the continuous nature of energy.

Explanation:

Discrete atomic energy levels mean electrons transition between specific energy levels. When electrons move from higher - to lower - energy levels, they emit photons of specific frequencies. This emission pattern indicates discrete energy levels rather than a continuous range.

Answer:

It indicates that electrons transition between specific energy levels, releasing specific amounts of energy.
