**LED Light Box & Optical Set

Comprehensive light and optics set which includes a 3 beam Ray Box (each beam available in dual colours – white or red) and an array of lenses and prisms, teacher’s notes and 9 pupil work cards. The set is an ideal accompaniment to any advanced study of light and optics with experiments to show refraction and reflection through various shaped prisms and lenses, the splitting of light into the rainbow colours, how internal reflection is used in fibre optic cables and the appropriate lenses to use to correct long and short sightedness.
