Main activities
K4a Coloured light
For the prism demonstration:
 two good-quality large prisms
 light source with intense white beam (not fluorescent)
 white screen onto which to direct spectrum
For the colour mixing demonstration:
 three light sources, preferably of variable intensity (e.g. ray boxes linked to low-voltage
supplies with variable voltage, encased to produce a circular beam of light)
 a red, a green and a blue filter, each fitted to one of the lights to give a red, a green and a
blue light. (Alternatively, you may have a dedicated piece of equipment for mixing the
lights.)
