• Measurement of wavelengths of the spectrum of atomic hydrogen;
• Comparison of the obtained spectrum with the predictions of the semiclassical and quantum theory of the structure of the hydrogen atom;
• Determination of an unknown gas by its spectrum.

The laboratory setup consists of a spectrometer, a power supply unit, and a set of line spectrum sources – gas discharge tubes. The spectrometer is based on a diffraction grating and a CCD matrix located at the focus of the mirror behind the diffraction grating. A special computer program is used to control the spectrometer and read information about the spectral composition of the analyzed sample.

The data are presented on the computer screen in the form of a spectrum - the dependence of the radiation intensity on the wavelength. The program has the necessary tools for analyzing spectra, including the ability to subtract the shadow spectrum. The sensitivity of the spectrometer is adjusted in the computer program working with it by changing the time of exposure of the radiation to the CCD matrix. The gas-discharge tubes included in the kit (except for the hydrogen tube) allow you to check the calibration of the spectrometer (using the mercury spectrum) and set a spectroscopic task to determine an unknown gas using its spectrum.
