Reflection and refraction

Laboratory eleven explored reflection and refraction. The design has remained nearly the same over the years, although this year I went ahead and put the independent variable for reflection in the first column and used o₁ for the object distance and i₁ for the image distances. Details are on the board shots at the end. I did not try to make the two tables consistent in the first column, intentionally reversing the order for the second table. I suggested the use of two tables and two graphs in Desmos.

I felt that the boards were about as clear as I have achieved in recent terms. Note that I have returned to switched columns between the two parts of the experiment. Yet to be determined if this will prove confusing.
