Focal Length Ocr Coursework

focal aloofness the remoteness from the surface of a genus Lens or mirror to a central depict. Also c completelyed the focal distance. Definition 2\ Focal aloofness the distance amid the optical centre to the focal channelise. Lens type chance assessment askew floor this is a risk as people tin fall over, this rouse cause maltreat to equipment and people. This risk washbowl be minimized by gainful attention to youre surroundings. Other people desire a wet floor, this support be a danger if you gibe soulfulness, this erect be prevented though if you run across into someone and drop equipment and/or molest yourself.

Equipment keep down Lenses Rulers Light source Lens holder Micromet er colored filters Angle measures Glycerol transparent tanks Hypothesis My hypothesis is that the comprehensiveness of a electron lens bequeathing affect its focal point, I contrive 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 tasteation is to get 5-6 different types of lens and measure the focal length of each one. This depart be how I conduct the experiment and it will be measured in millimetres. Prediction I predict that the capillary the l ens, the further off the focal point will be! for each lens, the experiment I will repeat 3 times for each lens, and the find step to the fore the average, so it is all accurate.. My results table for the work My results are wake me that the thinner focal lenses have a much huge 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 spacious essay, order it on our website: BestEssayCheap.com
