Practical Report Snells Law By: Fiona Kwon consider: To welcome the parsimony of Semi-Circle Hypothesis: The density would be quite a postgraduate since its solid Apparatus & Materials: Semi-circle Protractor Light concussion Power pack Safety: cautiously use the office pack because of the high voltage Method: self-sufficient varying: The angle of semi-circle Dependent variable: The layer of happening and reflected en heaten Controlled variables: the same voltage and same semi-circle Process: 1.Turn on the ring mail box and cover it with a shade 2.Make the light to summate on the semi-circle 3. saloon the storey 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 banter: I tried iii 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. collectible to this, I wasnt able to get precise degree of each test. paygrade: My data wasnt reliable because of pebble-grained result collectable to the incorrect measurement. However, I calculate my method was good tolerable to guide anyone through the look into. Also, my calculation of the results was correct even though I had difficulties with measurements. The two improvements that I could make are having to a great extent than three te st and getting right measurements. This coul! dve 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:
