Demonstration 1
Use the laser to show total internal reflection in an optical fibre and the prespex curved rod.
Resources
Use this power point presentation to discuss the basic background principles of coverting an anaogue signal into a digital signal and how the path of the optical signal affects performance; resulting in the design of multimode and monomode fibres.
Analysis
Equipment
White board with laser and semi circular glass block.
Safety
Do not shine lasers into people's eyes.
