Convex Lens Lab

Abstract: In this lab we measured various pick up and aim keeps that produced different pick up heights. We did so employ deuce different lenses, unity with a focal duration of +200mm, and one with a focal length of + ampere-secondmm. Both setups include a light source at one determination of an visual bench and a screen at the other. In some(prenominal) trials, we found that as distance of the object increases, the distance of the image becomes closer to the focal length of the lens. We in addition found that the magnification of each lens increases in a linear pattern. connive: In order to understand this lab, one must arrive in the lens equality. This equation is 1/f= 1/do+ 1/di. In this, f is focal length, do is the distance from the object to the lens, and di is the distance from the lens to the image. Magnification is also important. The magnification, or the change in size from the original object to the produced image, apprize be found by using the equ ation hi/ho= di/do. In this hi is the height of the image, trance ho is the height of the object. A diagram of these situations can be seen below. data-based/Discussion: We first used the +200mm lens and placed it on the optics bench, in between the light source and the screen. We locomote the lens forward and back so that various surface images were produced on the screen. We conducted the same procedure a second clock simply instead used a +100mm lens.

The data self-collected for both trials can be seen below. +200mm do (cm)di (cm)hi (cm)ho (cm)hi/ho (cm)do/di(cm) 81.227.3250.40.336206897 26. 5821352.63.094339623 62.530.52.550.50.488 ! 3063951.82.1 37.243.35511.163978495 8426.71.550.30.317857143 286110.552.12.178571429 25.687.914.352.863.43359375 40.639.9450.80.982758621 33.5526.551.31.552238806 +100 do(cm)di(cm)hi(cm)ho(cm)hi/ho(cm)di/do(cm) 125218.553.74.333333333 14.331.79.551.92.216783217 17.522.25511.268571429 22.517.83.550.70.791111111 13.534.510.552.1...If you hope to get a full essay, order it on our website: OrderCustomPaper.com
