During the week of Sept 14,we will be doing

In place of Experiment 1, The Eye

In preparation for this experiment you should read the first two pages of Section 34-7, Reflection and Refraction, in "Fundamentals of Physics" by Halliday, Resnick and Walker.

Some changes under:

Procedure

Section 4. Rather than calculate the index of refraction for every angle of incidence, Q _i, calculate sin Q _i and sin Q _r for all angles. Using all of these results make a graph with a linear fit on Kaleidagraph and obtain the index of refraction of the plastic material (Its commercial name is Lexan, its generic name is polycarbonate.)

Section 7. Although it is a lot trickier (why?), here too you could make a graph of the deflection, d, vs some function of Q _i and obtain a value of the thickness of the block, D, to which you can compare your measured value. If you do this it will be worth a small amount of extra credit (+ or ++ on your lab report grade).
