The wavelength is a property of a wave that is the distance between identical points between two successive waves. The distance between one crest (or trough) of one wave and the next is the wavelength of the wave. In equations, wavelength is indicated using the Greek letter lambda (λ).

A spectral line is a weaker or stronger region in an otherwise uniform and continuous spectrum, resulting from emission or absorption of light in a narrow frequency range, compared with the nearby frequencies. Spectral lines are often used to identify atoms and molecules. These "fingerprints" can be compared to the previously collected ones of atoms and molecules, and are thus used to id… Nettet21. apr. 2024 · A spectrum is a graph that shows the intensity of radiation at different wavelengths or the response of the atomic or molecular system to different …
