his telescope as a concave telescope‚ because it has a lens with inward curving surfaces. Till 1611 Johannes Kepler switched the concave eyepiece to a convex eyepiece. This allowed the telescope to gain a much larger range of distance. (http://www.antiquetelescopes.org/history.html)It also allowed the projection of images on to a flat white screen. The only problem was that the images were upside down‚ Johannes Kepler added a third convex lens to make the images the right side way. Even though

(refracting) called the “looker” by aligning a concave and a convex lens inside a metal tube. The convex lens refracted light to a specific point on the concave eyepiece making distant objects look magnified. When Galileo heard about the ’looker’‚ he decided to improveupon its design. Galileo called his model the ’telescope’. In his first attempt‚ Galileo built a three-power instrument containing a convex and a concave lens in 1609. He was more successful in further attempts to magnify objects

brain‚ let us see the world. Sensors in the skin respond to touch and allows us to feel. * * * * The seeing eye… Light enters the eye through the clear cornea. It then passes through the pupil and is focused by the lens on the retina. This thin layer covers the back of the eye and contains cells that are sensitive to light. When light hits the cells‚ they send signals to the brain. There‚ the signals are turned into pictures so we can see. Telescope

The optical principles that are in play here are perfect lens characteristic and transmitted light microscopy optical pathways. Interpupillary distance is the distance between the centers of the pupils of the two eyes. The way to determine what the interpupillary distance is with a device

learned in our lab‚ we need a good source of light for something to become clear. The mirrors that are used for the telescope cause the light to be reflected off of one mirror onto the other which then create a clear image from the large convex lens. “Because these light rays are parallel to each other‚ the reflector telescope’s mirror has a parabolic shape to focus the light rays back to a single point on the secondary telescope mirror. The secondary telescope mirror is flat and reflects the
