Key Stage 4
Meaning
Emission spectra are the specific wavelengths of light emitted by the electrons in atoms as they lose energy.
About Emission Spectra
- 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 electrons in high energy levels lose energy and fall to a lower energy emitting a specific wavelength of light when they do.
