Atoms experience electronic transitions when excited, leading to absorption of energy and emission of light.
When atoms get excited, they undergo electronic transitions where electrons move from one energy level to another. If the transition is to a higher energy level, energy is absorbed, resulting in the atom emitting a particular color of light.
The excess energy is released as photons when the atom or molecule returns to a lower energy state, a process known as emission. This emission of light can occur after absorption of a photon or as a result of a chemical reaction.
