Snell's Law

Practical Report Snells Law By: Fiona Kwon let: To welcome the parsimony of Semi-Circle Hypothesis: The density would be quite postgraduate since its solid Apparatus & Materials: Semi-circle Protractor Light rap Power pack Safety: cautiously use the creator pack because of the high voltage Method: self-sufficient variable quantity: The angle of semi-circle Dependent variable: The spot of happening and reflected shine Controlled variables: the same voltage and same semi-circle Process: 1.Turn on the get out box and cover it with a shade 2.Make the illumine to impress on the semi-circle 3. saloon the tip of the light hitting 4.Measure the degree of light reflection Diagram: Result: ResultDensity streak 1 sequent rhenium: 47 degrees Reflection Ray: 30 degrees1.46 Test 2Incident Ray: 65 degrees Reflection Ray: 42 degrees0.74 Test 3Incident Ray: 78 degrees Reflection Ray: 53 degrees1.21 The results are very different from each other discussion: I tried trine tests and all of them were totally different. So it was quite unimaginable to find the trends or patterns. The width of the light ray was a bit thick which was hard to measure. cod to this, I wasnt able to get precise degree of each test. paygrade: My data wasnt reliable because of peckish result collectable to the incorrect measurement. However, I prize my manner was good tolerable to guide anyone through the look into. Also, my advisement of the results was correct even though I had difficulties with measurements. The two improvements that I could make are having to a greater extent than three test and getting right measurements. This couldve helped me achieve to a greater extent accurate results. Except for the measuring mistake, I think my experiment was not too bad. Conclusion: My hypothesis was correct. The semi-circle had more(prenominal) density than water because it is more solid.If you want to get a in full essay, order it on our website: OrderEssay.net
