Description

In the experiment P6.1.4.4 one of the emission lines from a mercury gas discharge lamp is selected by interference filters and focused onto the photocathode. The countervoltage of the anode is varied and the resulting current is measured with high sensitivity. The variation of the characteristic curves under irradiation with different wavelengths leads to the determination of Planck's constant h.
