I felt that the lab did its job in helping to study the refraction of
light in glass. Everything came out with a relatively low percent error, giving us good results. Some causes of error that
could have affected the results were the thickness of the pencil lines. This made it difficult in measuring some of the angles.
Also the lining up of the pins through the glass proved to be a difficult task for people to pull off. This could have skewed
the results.
