Principle
If a circular disc separated into various differently coloured sectors is rotated by a motor so fast that the eye can no longer distinguish the colours, a mixed colour is then perceived. By varying the composition and size of the sectors, it is possible to give the ...
The aim of this experiment is to investigate the dispersion of light. In the course of this, the students' understanding of the refraction of light on crossing from air to glass or glass to air, respectively, is revised with reference to the dependenc ...
In the experiment on additive colour mixing, the students come to understand one of important, technical process for producing colour images. They should first investigate the overlapping of two different coloured light beams and then, in a fur ...
