The resultsof this experiment showed that there are multiple ways to get the focal point of converging and diverging lenses. For a converging lens in part 1, method one had asked to use the equation 22.1: 1/dO+1di¿= 1/f) to find F. Method two asked to go into the hallway outside the lab room and hold the lens so that the light from the end of the hall passes through the lens and to measure how far away from the wall the distance wasin order to find F. My partner (Jacob Smith) and I recorded this measurement of method two and compared it to the focal length of method 1 to find the percent difference. Our percent difference was 5.7%, which isn’t too bad considering we were eyeballing the measurements. In Part 2 of the experiment, we were asked to
