The Atomic Spectrum of Hydrogen When atoms are excited, either in an electric discharge or with heat, they tend to give off light. The light is emitted only at certain wavelengths that are characteristic of the atoms in the sample. These wavelengths constitute what is called the atomic spectrum of the excited element and reveal much of the.

The term spectrum is applied to any class of similar entities or properties strictly arrayed in order of increasing or decreasing magnitude.
