ANALYSIS So there will be 4 data sets. For each data set follow the analysis steps: 1. enter all data into excel 2. create a graph of angle of incidence on horizontal axis and angle of refraction on vertical. Label all axes. Include in report. 3. Now transform the data to create two new columns containing the sine of the angles. 4. create a new plot of sin(9i) on the vertical axis and sin(Br) on the horizontal. (Note this is flipping the horizontal and vertical axis from step 2.) 5. Add a linear trend line. Include graph of transformed data with linear t with equation in your report. 6. Record the slope of the line from step 5 to the data table and consider it as experimental value of nrfni. 7'. Determine the theoretical slope or theoretical value of mini from the simulation page. Record it on the table. 8. Find percent error between theoretical and experimental value of mini. PROCEDURE: This protocol will generate data that you will be able to analyze. Do this protocol for each type of interface (the types of interface are listed in Table 1). First choose the upper and lower material using the controls on the right. Now, place the protractor to measure the angles as shown in Figure 1. Now adjust the position of the laser to an angle of incidence. Record the values of the angle of incidence and the angle of refraction in a table. Repeat for angle of incidence from 0 to 90 in steps of 10 degrees.
