MA Meeting: 24.12.10

During our MA session we experimented with an overhead projector to see the capabilities of using it as the light source for our installation. We came to the conclusion that we would at our meeting on the saturday ahead remove and reposition some of the parts in order for us to use it in our experiments.

Concave Mirror: 24.11.10

A concave mirror, or converging mirror, has a reflecting surface that bulges inward (away from the incident light). Concave mirrors reflect light inward to one focal point, therefore they are used to focus light. Unlike convex mirrors, concave mirrors show different image types depending on the distance between the object and the mirror.
These mirrors are called "converging" because they tend to collect light that falls on them, refocusing parallel incoming rays toward a focus. This is because the light is reflected at different angles, since the normal to the surface differs with each spot on the mirror.
