Refraction dramatically illustrated

The effect would also be dependent on the round shape of the glass. I don't believe the reversal would be seen if a rectangular aquarium were passed in front of the arrows.

  1. Quite an interesting comment on politics and politicians I think...

  2. It is dependent on both the curvature of the glass and the placement of the camera and paper. The reversal happens because the lens is set up to be a relay imagining system. The relative position of the two determines the magnification which needs to be 1 to 1 for this effect to work.

    1. In layman's language, "it only works at one distance."
