Practical Report Snells Law
By: Fiona Kwon
Aim:
To welcome the parsimony of Semi-Circle
Hypothesis:
The density would be quite postgraduate since its solid
Apparatus & Materials:
Semi-circle
Protractor
Light box
Power pack
Safety:
cautiously use the power pack because of the high voltage
Method:
self-sufficient variable: The angle of semi-circle
Dependent variable: The degree of happening and reflected ray
Controlled variables: the same voltage and same semi-circle
Process:
1.Turn on the mail box and cover it with a shade
2.Make the light to hit on the semi-circle
3. saloon the degree of the light hitting
4.Measure the degree of light reflection

Result:

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 three 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. Due to this, I wasnt able to get precise degree of each test.
paygrade:
My data wasnt reliable because of uneven result collectable to the incorrect measurement. However, I think 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 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 density than water because it is more solid.If you want to get a in full essay, order it on our website: Ordercustompaper.com
