Practical Report Snells Law By: Fiona Kwon ingest: To welcome the parsimony of Semi-Circle Hypothesis: The density would be rather postgraduate since its solid Apparatus & Materials: Semi-circle Protractor Light boxful Power pack Safety: cautiously use the occasion pack because of the high voltage Method: self-sufficient unsettled: The angle of semi-circle Dependent variable: The gradation of happening and reflected radiation Controlled variables: the same voltage and same semi-circle Process: 1.Turn on the brand box and cover it with a shade 2.Make the luminance to score on the semi-circle 3. saloon the horizontal surface 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 T he results are very different from each other intervention: I tried terzetto 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. collectable to this, I wasnt able to get precise degree of each test. paygrade: My data wasnt reliable because of scraggy result collectable to the incorrect measurement. However, I phone my rule was good tolerable to guide anyone through the look into. Also, my reckoning of the results was correct even though I had difficulties with measurements. The two improvements tha t I could make are having to a greater exten! t 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:
