Demonstration: Three simple demonstrations of the refraction of light at an air-water interface.

Practical Activity 14-16

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

Practical Activity 14-16

Demonstration: This can be shown to a sixth form class as a fun demonstration of light interference.

Practical Activity 14-16

Demonstration: Both particles and waves reflect in the same way as light.

Practical Activity 14-16

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

Practical Activity 14-16

Demonstration: Shows refraction is caused when plane waves change speed as a result of a change in the depth of water in a...

Practical Activity 14-16

Two thinking models of light were argued about for many years. In the 17th century, Isaac Newton decided in favour of a...
