Colours of Light

Added by Craig Napier on Dec 15, 2008

This activity introduces the primary and secondary colours of light. Students move coloured torches to mix the light and record their results in a table to see how the secondary colours are formed. A simple model of the pixels in a TV screen gives a practical application of colour addition.
