The demonstration of refraction using a ripple tank is tricky, and it is a good idea to practise this.
Demonstration: Three simple demonstrations of the refraction of light at an air-water interface.
Demonstration: Refraction at an air-water interface and total internal reflection.
Demonstration: This can be shown to a sixth form class as a fun demonstration of light interference.
Demonstration: Both particles and waves reflect in the same way as light.
Demonstration: Particles and waves refract differently. Only waves refract in the same way as light.
Demonstration: Shows refraction is caused when plane waves change speed as a result of a change in the depth of water in a...
Two thinking models of light were argued about for many years. In the 17th century, Isaac Newton decided in favour of a...
Why does the angle of incidence = the angle of reflection ? One answer explored earlier is an appeal to the rules about rays...
- make connections to prior studies of reflection, propagation and refraction - exploit the simple idea of being"in-step" -...
This episode starts from the phenomenon of refraction and moves on to Snell’s law.
The coin reappears because the water bends, or refracts, the light travelling from the coin so that it can now reach your eye.
