WebA wave of light has a wavelength, defined as the distance from one crest of the wave to the next, and written using the symbol . The wavelengths of visible light are quite small: between 400 mm and 650 nm, where 1 nm = 10-9 m is a ``nanometer'' - one billionth of a meter. Red light has long wavelengths, while blue light has short wavelengths. WebFeb 21, 2024 · In order to return to its ground state, the electron releases the additional energy in the form of light. Different metal electrons emit different wavelengths of light to return to their respective ground states, so the flame colors are varied. These flames can be used to produce atomic emmision spectra of the elements combusted.
