Answer is: emission spectrum.
When atom or molecule moves from a high energy level to a lower energy level than chemical element or chemical compound emits spectrum of frequencies of electromagnetic radiation with specific energy. That energy is equal to the energy difference between the two levels.

The light spectrum that results from the light produced by an excited electron moving from a higher energy level back down to a lower energy level is an emission spectrum. The emission spectrum is formed by the electromagnetic radiation released by the transition in energy state.
