Answer:
When an atom in an excited state returns to its ground state, the excess energy is released. This excess energy can be released in the form of electromagnetic radiation, such as visible light, ultraviolet light, or infrared radiation. The specific wavelength or energy of the released radiation depends on the energy difference between the excited state and the ground state of the atom. This release of energy is often observed as the emission of photons or the characteristic colors of light emitted by certain substances when they are excited and then return to their ground state.
