Experiment setup: 11.12.10



Due to having to wait for the post to arrive at Immos this morning. Myself, Sally and Namak meet up and waited for immo and the new torch to arrive, in some ways this was a blessing as we managed to get some beautiful images using the parabolic mirror placed on the table reflective side facing up and an iphone 4 camera light.

The results were memorising from just the light reflections on the celling of our basement room. The shapes which the parabolic mirror created were stunning, we also experimented using heat sources to capture some Schliern effects with in these light sculptures upon the celling, which gave are most successful results yet. The light images gave a 3D feel you could really see the depth of the light shapes and the Schliern effect inside the light.

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.
