Light: Mixing Primary, Secondary and Complementary Colours

There are two nice links below which show how light beams are mixed.
This link shows how varying the intensity of the primary colours, can lead to the creation of all colours. Your standard CRT TV uses this type of "colour mixing" to achieve the colours of the images on the screen.
This is an excellent applet to show the mixing of the 3 Primary Colours (Red, Blue and Green). It also shows very clearly the "Secondary Colours" and makes the "Complimentary Colours" very easy to identify.

Ray Tracing for a Convex Lens

Hi Folks,

Were moving onto "Ray Tracing" diagrams for Convex Lenses. Click the video link on the right hand side of this page to view a sort clip about ray tracing.

Heres a nice link to get everyone started on convex lenses. Also have a look at the applet on the site. It shows you all the different images which can be formed using a convex lens.

If any of you folks find some more interesting links... Post them up ;-)
