This is a simple setup to show the difference between Convex Mirror Telescopes, and Convex Lens Telescopes, using white light and mono-chromatic light. The Concave Mirror Telescopes are the common

    Correction, an ellipse is not a paraboloid, but I can't be bothered to make a paraboloid

    @Nunnhem An ellipse is also a paraboloid

    If you look at the image from a poorly focused projector, you'll see yellow and blue areas on each side, this is because of chromatic aberration. It is also the effect that allows prisms to create spectra

    The cross section of a lense, is an ellipse. A circle, in 2D would work as a lense

    What do you mean by "unclear"?

    aberation results in unclear lenses with different focal points yes?

    This isnt realistic. Lenses are paraboloids, Not elipses.

    this would have been great last year when my teacher caught me using powder toy to mess around with lenses in a science lesson about lenses and then made me reaserch lenses on powder tor to get an acurate simulation... but there wernt any
