Homework Help: Easiest lens project?

  1. May 17, 2007 #1
    Everyone in our class needs to build a lens optical device such as a projector, camera, copier, telescope, microscope, solar cooker, etc. We will need to include a ray tracing diagram. Has anyone ever made a simple device with lenses? What do you think will be the easiest and cheapest? Thanks

    Telescopes are very easy and cheap. A microscope would be relatively easy as well. Solar cooker? Hah.

    Any other opinions?

    I've read some informational articles about building telescopes and it says that all you need is 2 magnifying glasses? Is it really this simple? If so, I'm going off to the store to buy magnifying glasses. =] Does anyone know where they sell cheap ones at? Thanks.
