The device has a built-in photodiode, LEDs of various wavelengths are used as monochromatic light sources.
The emitted light passes through the opening of the ring-shaped anode and contacts the surface of the cathode.
In the photoeffect, a photon transfers its entire energy (E = h * f) to an electron upon impact.
Part of the energy is required to force the electron out of the metal surface (electron affinity).
The remaining energy is then at the electron?s disposal as kinetic energy.

Ekin = h x f – ?

The critical voltage for the five available wavelengths is measured within this experiment.
All further calculations are based on this.
