Positions of L-dips (relative to the unperturbed wavelength of a spectral line) scale with the electron density Ne roughly as Ne1/2, while positions of X-dips are almost independent of Ne. L-dips and X-dips phenomena are interesting and important both fundamentally and practically. The fundamental interest is due to a rich physics behind each of these phenomena. As for important practical applications, they are as follows. Observation of L-dips constitutes a very accurate method to measure the electron density in plasmas – the method that does not require the knowledge of the electron temperature. L-dips also allow measuring the amplitude of the electric field of Langmuir waves.
