PLAN the p[an for my audition is to get 5-6 different types of lens and measure the focal length of each one. This volition be how I conduct the investigate and it will be measured in millimetres. Prediction I predict that the capillary the le ns, the further off the focal point will be ! for each lens, the experiment I will repeat 3 times for each lens, and the find erupt the average, so it is all accurate.. My results table for the work My results are covering me that the thinner focal lenses have a much 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 near essay, order it on our website: BestEssayCheap.com
