Key Features
Set of 6 transparent coloured spades
Light passes through each piece, showing the colour it transmits
Overlapping two pieces produces a new colour effect
Used with a lamp, ray box, filter holder or optical bench
Students hold one spade in the light path, note the transmitted colour, then lay a second over it and record what changes. Working through the combinations shows how colour filters remove parts of the light and how the colour seen depends on what is transmitted. The Transparent coloured spades can be supplied on export terms to Jordan, Saint Vincent and the Grenadines, Albania, Malta and Brazil.
