EM4.2 Electric Flux
This uses a vu graph and a plexiglass contraption. The apparatus has a piece of plexiglass in which holes have been drilled that rotates about an axis on its side. On the vu graph, when the plate is parallel to the light source, the class sees all the dots perfectly. An the angel between the light source and the plate is increased, the image of the dots changes. They get weaker with the increase of angle. This shows the cosine dependency of flux.
