Electric Field Mapping
1. In the lab we found voltage points to trace equipotential surfaces and map electric fields
produced by a potential difference. The theory behind this was that equipotential lines do not
intersect with one another, they do interse
The Double Slit

calculate the wavelength. When light is passed through the two-slit
experiment set up it is noticed that the light interferes constructively. This
