work as well as to test the validity of the Thin Lens Equation. 2. Theory Lenses and mirrors are used to change the direction, orientation, and magnification of an object. This experiment used lenses known as thin spherical lenses. These lenses are called thin spherical lenses because they have spheres on each surface with large radii compared to the small thickness of the lenses. The focal length (f) of the lens is determined by using the Thin Lens Equation and substituting the objects distance (o)

generally used to describe the severity of the myopia, as this is value of the lens to correct the eye. Figure 2 shows the effect of concave lens in correcting the myopic eye. Power of a Lens: In concave lens, a collimated beam of light passing through the lens is diverged. The power of the lens can be calculated from the focal length of the lens. P = 1/f, where, P= Power of the lens and f = Focal length of the lens Simulation: The project uses Maya as the simulation tool for obtaining the 3D

Project Description for Programmer/Artist Collaboration I am interested in using computer vision and automation to select and sort internet images. I will briefly describe the project I want to accomplish: The images will be downloaded from or found in Google image searches. The program will select images if it contains an object similar to an original object or image, or if the image is similar to an original image or composition. Next, each image would be arranged as an individual frame of video

The lens of an eye is made up of water and protein. The protein is arranged in a way that keeps the lens clear and allows light to pass through. A cataract forms when some of the protein clumps together and begins to cloud a portion of the lens. Over time it grows larger and affects your vision.

them. The simplest microscope of all is a magnifying glass made from a single convex lens, which typically magnifies by about 5–10 times. Microscopes used in homes, schools, and professional laboratories are actually compound microscopes and use at least two lenses to produce a magnified image. There's a lens above the object (called the objective lens) and another lens near your eye (called the eyepiece or ocular lens). Each of these may, in fact, be made up of a series of different lenses. Most compound

TASK 1 Comparing light and electron microscope Note:- A microscope is an instrument used for viewing a tiny object that cannot be seen with our naked eyes. The microscope is an important instrument found in the laboratory. We have two types of microscope. Light Microscope and Electron Microscope. The light Microscope is one which can be illuminated by light while an electron microscope is one which can be illuminated by electron. Electron microscope is expensive and not portable compared to the light

appropriate for his age. As he plays the video game, you can see that even though he has glasses to help him see he is squinting to be able to see the TV that is right in front of him. By the time an individual reaches middle adulthood, his or her eye lens begins to thicken and the muscle that causes the eye to focus to objects starts to get weaker. This is evident during the observation when the man is having a hard time seeing and focusing on the TV (Berk, 2010). On a cognitive perspective what

[pic] HISTORY OF MICROSCOPE Oddly enough, the compound microscope was invented before the single lens microscope. But the instruments were not very good to start with and much more could be seen with very small lenses of short focal length. In about 1597 two Dutch eyeglass makers, Zaccharias Janssen and his son Hans were experimenting with lenses in a tube. They observed that nearby objects viewed through two lenses in line were magnified. Their device was the first compound microscope
