Total Internal Reflection

Refraction in a tank of water

Demonstration: Refraction at an air-water interface and total internal reflection.

Practical Activity 14-16

Demonstration: Particles and waves refract differently. Only waves refract in the same way as light.

Practical Activity 14-16

Total internal reflection (TIR) is a consequence of refraction.

Lesson 16-19

Almost all the light from the torch is reflected every time it hits the edge of the stream of water, so the light follows the...
