In experiment P6.1.4.4, a specific emission line from a mercury gas discharge lamp is chosen using interference filters and directed onto the photocathode. The anode's countervoltage is adjusted, and the resulting current is precisely measured. The change in characteristic curves under different wavelengths allows for the calculation of Planck's constant h.
