For the experiment I found the focal length, and set up the lens and light source at that distance. I used just paper for a screen to produce the real images created.
WebThin-Lens Equation:Newtonian Form. In the Newtonian form of the lens equation, the distances from the focal length points to the object and image are used rather than the distances from the lens. Newton used the "extrafocal distances" x o and x i in his formulation of the thin lens equation. It is an equivalent treatment, but the Gaussian form ...
