Final answer:
The release of energy corresponding to electrons transitioning from higher to lower energy levels results in electromagnetic radiation, which is visible during events like fireworks displays.
Step-by-step explanation:
When electrons transition from higher to lower energy levels, they release energy, which often manifests as electromagnetic radiation, such as visible light. This phenomenon underpins the basis for atomic emission spectra, where each element displays a unique spectrum due to its distinct electronic structure. The released energy corresponds to the difference in energy between the two levels, described by the equation ΔE = hf = E₁ - Ef, where ΔE is the change in energy, h is Planck's constant, f is the frequency of the emitted photon, E₁ is the initial energy state, and Ef is the final energy state. In a fireworks display, the light we see is the result of such electron transitions, with different elements emitting different colors.
