Emission spectra are the specific wavelengths of light emitted by the electrons in atoms as they lose energy.

An emission spectrum is made by providing energy to a material and focusing any light emitted through a prism to separate the colours.

The spectrum of white light is a continuous change of colours with all wavelengths having the same intensity.

An emission spectrum is a set of specific wavelengths with a high intensity. This appears as bright lines of colour on a spectrum.

A emission spectrum is created when excited electrons (electrons in high energy levels) lose energy and fall to a lower energy level emitting a specific wavelength of electromagnetic wave when they do.


This diagram shows an excited electron losing energy by emitting an electromagnetic wave. As it does this the electron falls back down to a lower energy level.
