Description

In the experiment P6.2.2.3 the spectral lines of a high pressure mercury lamp are investigated with a high-resolution spectrometer assembly using a holographic grating. The grating works in reflection, leading to a high intensity of the lines. Different lines are observed and their wavelengths determined, especially the yellow, green, blue, violet and also the ultraviolet line. Some lines are investigated closely, e.g. the yellow double line, and the splitting of the wavelengths is determined.
