Description

The experiment P5.4.4.1 demonstrates the Kerr effect for nitrobenzol, as the Kerr constant is particularly great for this material. The liquid is filled into a small glass vessel in which a suitable plate capacitor is mounted. The arrangement is placed between two polarization filters arranged at right angles, and illuminated with a linearly polarized light beam. The field of view is dark when no electric field is applied. When an electric field is applied, the field of view brightens, as the light beam gets elliptically polarized when passing through the birefringent liquid.
