Unformatted text preview: Dylan Bloom Olivia Nixon Joe Durantini Lab 6: Lenses Introduction: The purpose of this experiment was to gain hands on knowledge of how some simple lenses (concave and convex) affect the object-image relationship. The goal was also to calculate the focal length of both a converging lens and a compound lens by projecting a real image through the lens. By measuring the object distance and the image distance we were able to use the equations below to calculate the focal length and magnification: Procedure: Part A: Converging Lens First we set up the light source, object, lens, and screen (in that order) on a track. We then set the lens 22 cm away from the object and focused the image on the screen by adjusting the distance of the screen from the lens. We then recorded the object distance and image distance as well as the object height and image height. Then we moved the lens, in increments of 1 cm, further away from the object and adjusted the screen accordingly until reaching 42 cm, recording the values that changed along the way. Finally, we graphed the inverses of the object reaching 42 cm, recording the values that changed along the way....
