An emission spectrum is a spectrum of the electromagnetic radiation emitted by a substance that has absorbed energy. When atoms or molecules absorb energy, they can become excited and move to higher energy levels. When these electrons return to their original (or ground) state, they release energy in the form of light. The wavelengths of this emitted light correspond to specific energies and are characteristic of the particular element or compound.
