How to Make a Simple Refracting Telescope (Monocular)
This video shows how to build a simple refracting telescope, also called a monocular or a spyglass, using two lenses. One lens is double convex (converging) and one is double concave (diverging). This results in a magnified right-side-up...

Understanding Lens Formation Using Radar Diagrams
The video is about using radar diagrams (also known as ray diagrams) to investigate how the type of lens used and the distance between the lens and object affect the formation of an image. The video shows four different ray diagrams,...
