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.
