Question
1. Carpenters and other crafts men seldom use protractors to measure angles. Based upon your experiences during this lab, comment on why that is probably a good idea. (10 points) 2. Complete the table below by filling in the last column ofthe table using Snell's Law. Do not use any measured data for this part, assume an ideal experimental setup as shown in the diagram above. Please show all your work, including diagrams. (50 points) Ray Protractor Snell (theory) Trigonometry 3. Compare your theoretical and experimental numbers. What is (are) a significant source(s) of error? (10 points)Explanation / Answer
1) - protractors are transparent. they can be used to trace the light ray with the lines on it.
- the refraction that occurs when the light rays enter the protractor is cancelled out, when it comes out of the protractor.
2)using snell's law
n1sin 01 = n2sin 02
1 x sin 58 = 1.5 sin 02
= 41.5 degree
the angle of refraction in plastic is 42.
angle B = theta 2 .... by corresponding angle
angle c = theta 1....... by alternate opposite angle
3)
- human error
