What is the wavelength emitted?
When the electrons fall back down and leave the excited state, energy is re-emitted in the form of a photon. The wavelength (or equivalently, frequency) of the photon is determined by the difference in energy between the two states . These emitted photons form the element’s spectrum.
Is light emitted when an atom is excited or de excites?
Light is emitted when an electron: makes a transition to a lower energy level. The electron in an atom is boosted to a higher orbit and excited. When the electron returns to its original state, it de-excites and emits a photon of light.
