Description

In the experiment P5.7.1.1, the spectrometer is used to observe the spectral lines of inert gases and metal vapors which have been excited to luminance. To identify the initially unknown spectral lines, the angles of deviation are measured and then converted to the corresponding wavelength using the calibration curve.
Note: as an alternative to the prism spectrometer, the goniometer can also be used to set up a grating spectrometer (see P5.7.2.1)
