Many demos are suggested using many different types of wave motion. The first time you set these up keep diagrams or exact...
Class demonstration: This demonstration shows that a beam of light is diffracted as it passes around a wire, highlighting the...
Demonstration: To show that a laser beam can easily be modulated to carry information.
Demonstration: This can be shown to a sixth form class as a fun demonstration of light interference.
Pupils will very often agree that to be able to see, light must enter the eye. However, it is possible to set up situations...
We'd suggest that it pays to emphasise that laser light is reflected from the rough surface of the wall in all directions...
This episode considers uses of lasers, and the underlying theory of how they work.
This demonstration shows that a beam of light is diffracted as it passes around a wire, highlighting the wave nature of light.
