About This Product
With several parallel beams on one board, students can trace refraction through blocks and lenses, reflection from mirrors and the focal points of lenses. The magnetic backing lets a teacher show the same experiments upright to the whole class. Schools, colleges and institutes in Serbia, Croatia, Barbados, Togo, Republic of the Congo and New Zealand can order the Laser Ray Box from Educational Instrument.
