In this experiment, the students investigate the possibility of
reuniting coloured light to white light. In addition to
strengthening their knowledge of the dispersion of light by a
prism, the foundation for the understanding of additive and
subtractive colour mixing is laid down, without which many of the
technical-optical phenomena known to them cannot be explained
(colour television, colour prints, colour slides, colour printing,
The latter primarily aids in the investigation of secondary colours
by the fading out of parts of the coloured light before reuniting
it. It should not to go unnoticed that, in this experiment,
evidence for the validty of Isaac Newton's concept for the
composition of white light from many colours can be supplied.
- Multifunctional light box - All-in-one: Can be used for geometric optics on the table, colour mixing and on an optical bench
- Extension with others sets at anytime, no additional light sources needed, recognition value for students
Can coloured light be reunited? Investigate the possibility of
reuniting white light which has been split by a prism.
