ASK design features laboratory workshop on atomic physics taking into account the new SI-2019 system



Changes in the SI-2019 system are proposed to be taken into account by cor­recting of the educational experiment in atomic physics. From the data on the emission spectrum of atomic hydrogen, it was proposed to calculate not only the Rydberg constant, but also the effective mass of the electron, the re­fractive index of air. It is shown that a digital spectrometer allows one to quan­titatively study the isotope effect of a proton.
