Description

In the experiment P5.3.4.4 the wavelength λ of the green spectral line of a Hg spectral lamp is determined. To measure the coherence length the positions of the movable plane mirror are measured where interference can barely be seen. From the difference in path length the coherence length ΔsC, the coherence time ΔtC and the line width Δν of the spectral line are determined.
