In this setup, various optical phenomena like refraction, reflection, and total internal reflection will be investigated. With the laser module, mounted on the moving rail, the laser light can be directed on different samples. The set of samples includes a plane-parallel plate, transmission cavity, prism, and a moving table with small prisms and lenses. The traces of the laser beam can be seen very well in the setup. The beam will be projected on a screen and small beam terminator. The different phenomena will be investigated using special templates prepared for each test, on which all beam trajectories have to be drawn.
