About This Product
Seeing light emerge from the far end of a curved fibre makes total internal reflection concrete for students. The kit links refraction and critical angle lessons to how communication signals travel through optical fibre cables. Educational Instrument can dispatch the Optical fibre kit to laboratories in Bolivia, Argentina, Saudi Arabia, Chad, Italy and Saint Vincent and the Grenadines.
Frequently Asked Questions
Why does light stay inside the bent fibre?
Light inside the fibre undergoes total internal reflection at its walls, so it is guided along the fibre without escaping from the sides.
