Description

In experiment P5.3.4.5 the coherence lengths and spectral widths of the green spectral line of a Hg spectral lamp and a high pressure mercury lamp are determined and the results are compared. The higher pressure in the high pressure mercury lamp leads to a significant broadening of the spectral line causing a shorter coherence length.
