G482 Electrons Waves and Photons
The G482 Unit has some varied content and it is very easy to get lost in a Quantum world or some of the finer points of waves. Remember you are doing the basics and you must learn them carefully before you try anything to advanced. Also any Wikipedia links here are to start you off, you don’t need everything in the page as they go to PhD level!
