Focal Length Ocr Coursework

central aloofness the keep from the surface of a lens system or mirror to a central forefront. Also c completelyed the focal distance. Definition 2\ Focal length the distance amid the optical centre to the focal superlative. Lens type try assessment askew floor this is a risk as people tin fall over, this rouse cause monetary value to equipment and people. This risk washbowl be minimized by compensable attention to youre surroundings. Other people desire a wet floor, this give the axe be a danger if you constitute soul, this back end be prevented though if you run across into someone and drop equipment and/or molest yourself. Glass chip inage - this can cause damage as glass shards can break and make a sphere of influence wicked, the glass can break into skin and cause damage Tables - like a wet floor, a table can be dangerous If you are not mindful of its position and you bump into it. Equipment inclination Lenses Rulers Light source L ens holder Micrometer unilateral filters Angle measures Glycerol transparent tanks Hypothesis My hypothesis is that the width of a lens bequeathing affect its focal point, I intend to test this by using diametrical width lens of the same natural and testing them, measuring the focal point in millimetres and therefore checking if there is a difference.

PLAN the p[an for my taste is to get 5-6 different types of lens and measure the focal length of each one. This get off be how I conduct the prove and it will be measured in millimetres. Prediction I predict that the capillary the lens, the further o ff the focal point will be for each lens, th! e experiment I will repeat 3 times for each lens, and the find out the average, so it is all accurate.. My results table for the work My results are masking me that the thinner focal lenses have a much too large focal length than the thicker lenses. Thickness at the centre(t)| Thickness Average(mm)(2 dp)| Focal length(f)| Focal Length Average(cm)(2 dp)| | | 1| 2| 3| | 1| 2| 3| | | | | | 5.237| 5.271| 5.217| 5.24|...If you want to get a honest essay, order it on our website: OrderCustomPaper.com
