Geometrical optics

The Schlieren photographs taken in this lab, attached in Appendix B, show how the flow develops with respect to the flow exit pressure that is controlled by the opening of the valve. Schlieren photography is made possible by the variation of refraction index of gases in different density. To be more specific, the Schlieren photographs are taken in an environment with a collimated light. Without external interference, a collimated light should propagate in parallel for an infinite distance;…

My first image, which conveyed detail, depicted a banquet being served on the Dean Dome basketball court. I chose to use this image for several reasons, including its repetitiveness, unique color, and relative uniformity. Although many of my classmates chose to photograph minute details of a single subject, such as a piece of wood or stream of running water, I found that this photograph was more expressive of detail in a much larger subject. When taking this photo, I intended to capture as many…

I start creating my work by replaceing traditional lighting associated with photgraphy with the lighting of tv screens. Then I continue following an image by also removing the figure as the main portion of the image , to make the figure less important. Finally, when i capture these images I use long exposures which creates a stillness of the image, except for the human figure, which creates this blurr and motion in the image. My images are a series of self portriats. I spend time setting up…

The goal of the first part of the experiment was to examine the focal lengths of various thick lenses, spherical aberration, and 1D magnification. First, we observe that the focal length does not seem to change when we move the lens closer and farther away from the box. Then, we find that the light rays converge after passing through the bi-convex and plano-convex lens and diverge after passing through the bi-concave lens. Therefore, the focal length of the bi-concave lens is negative. We also…

Photography Photographers work with people everyday they provide people memories and records of events that have happened. I have chosen this career because I love taking pictures of action and emotion of in that moment. I really enjoy witnessing people's reaction to what they look like in that moment of happiness, sadness, and other emotions. When they look at the picture they want to remember things that you don't always see. Photography is what I want to do in my life, and I’d also love…

There are so many options and ideas around photography in advertising, I love a challenge and during my research I came across the idea to photograph gemstones. Fire and brilliance are two categories under which we would find gems stones and diamonds. Optical gemology is the identifications term used to describe the characteristics of the color, transparency and luster of these breathtaking stones. The lusters the quality of light that reflects from the surface of a stone, observing the…

I. Optical Art Background/History Optical Art is a type of art that using the “illusion” of seeing something that does not exist. This art style tricks the brain into seeing things that do not exist or things that are not actually happening. There is a lot of repeating lines, shapes, and images, which sometimes appear to be moving. The term Op Art first appeared in Time Magazine in October 1964. Op Art is still a big part of the today's world and culture. Optical illusions are awesome to…

is only natural that the great thinkers of antiquity were curious about the nature of vision, and inseparably, that of light itself. In the manner characteristic of ancient science, many common ideas about optics were “hit or miss”, so to speak. Certain Greek thinkers had hypotheses about optics which are more or less in line with modern principles, but many held firmly to ideas which are at odds with the current understanding of reality. I discuss extramission theory (a hallmark of Greek…

I. Introduction A. On an adventure to Milwaukee any tourist would go to the Milwaukee County Zoo. The first stop is always the penguin habitat. B. Have you ever paid attention to what species it is or where they came from? C. When we see penguins it is always in the zoo or part of an animation production. Here are 3 ways to analyze penguins from what is shown on the big screen to the natural habitat. II. When I think of penguins I think of penguins of Madagascar or the Pittsburg penguins. III.…
