Step 1: Make Jello
Step 2: Setup
Step 3: Place Jello
Step 4: Collecting Data
Step 5: Calculating the Refractive Index of Jello
Our graph (shown above) had a best fit line with a slope of 1.21, which told us that our experiment supported that the refractive index of jello is 1.21.
Upon completion of this experiment, we learned many things. We realized that it can be difficult to see the refracted light from a red laser in cherry Jello. This difficulty could have resulted in refraction angle measurement errors, which will lead to an incorrect index of refraction. In future experiments we would advise using a lighter color. However, we believe that this is a beneficial experiment for learning because this method can be used to find the index of refraction of most transparent materials, which will be useful for any optics student.
