What happens when the electrons relax? Since the energy of these photons directly corresponds to the gap between different energy levels in the atom, we can study the energy structure of the atom by measuring the wavelengths of these photons. As the light emerges after being reflected by the grating, these tiny lines cause the reflected light to interfere with itself in such a way that the different wavelengths of the light to appear in different positions to the left and right of the original direction in which the light was traveling. Due to conservation of energy, the amount of energy in an emitted photon will exactly match the amount of energy lost by the electron as it moves to the lower energy state.
