On the right you see a simulation of the controls and output display of an experiment which you will use to measure the index of refraction of an unknown (but transparent) substance.

1. Record the code number.

2. For at least 10 different trials, adjust the angle of incidence, and record both the angle of incidence and the angle of refraction.

3. Since the angles were in degrees, you may directly calculate the Index of refraction using the formula Sin(i)/Sin(r) OR you may use a spreadsheet to do the work for you. HOWEVER, be careful. Some spreadsheets expect angles to be in radians, not degrees.

4. When you have enough trials, calculate the average index of refraction.

5. Your conclusion should be: The index of refraction for the sample having code number ..... was found to be .....
