Atomic spectra of two-electron system: He, Hg
Article No: P2510810
The spectral lines of He and Hg are examined by means of a diffraction grating. The wavelengths of the lines are determined from the geometrical arrangement and the diffraction grating constants. Spectral lines of various elements can be determined with high precision Simple setup for high ranking experiments HV power supply with high safety standards makes experimentation safe Determination of the wavelengths of the most intense spectral lines of He. Determination of the wavelengths of the most intense spectral lines of Hg.
