Interference at a mica plate according to Pohl
Principle: Monochromatic light falls on a plane parallel mica plate. The light rays, reflected at the front surface as well as at the rear surface, will interfere to form a pattern of concentric rings. The radii of the rings depend on the geometry of the experimental setup, the thickness of the mica plate and the wavelength of the light.
Tasks: The experiment will be performed with the light of a Na-lamp and with the light of different wavelengths of a Hg-vapour tube.
1. The thickness of the mica plate is determined from the radii of the interference rings and the wavelength of the Na-lamp.
2. The different wavelengths of the Hg-vapour tube are determined from the radii of the interference rings and the thickness of the mica plate.
