Term 1 Wk 3 - Critical Angle and Total Internal Reflection

Practical Experiment on Critical Angle and Total Internal Reflection

4E1 pupils had a session of experiencing for themselves first hand the light phenomenon of total internal reflection when light travels from an optically denser medium to an optically less dense medium. The pupils were given a set of ray box and a semi-circular glass block. The theory concept was covered earlier, but given hands-on experience would help them to internalise the concept better.

A video would help pupils in recapping the concept which was covered so that they can relate better to the theory aspect.
