The Diverging Glass

To create this image, I used a crystal glass and took the photograph looking directly through it. Due to the cupís construction, there were little dips near the bottom that produced their own smaller and curved separate views of the same landscape. The reason for the curved smaller images is due to the fact that the dips and bottom of the cup have the shape of a concave lens. Concave lenses have their outer side curving inward which causes the parallel incoming rays, also known as incident rays to diverge. The reason for the multiple images is due to the fact that the dips each had different angles, so when the incident rays hit them it created another separate view with the concave lens image properties.
