Set of apparatus for a comprehensive and easily understandable introduction to the basic principles of refraction and reflection of light by means of demonstration or student experiments. The laser can be easily attached via its built-in magnet and aligned on the end of the metal base. The rotating optical disc has an angular scale with 1° divisions and marked lines to position the elements. The set includes a semi-circular disc and an equilateral prism for use in optical experiments, as well as a plug-in mains-adapter power supply and a battery compartment (batteries are not included in the apparatus as supplied).
