that was useful in helping me determine the order was 400x. This magnification allowed me to see that the yellow color thread was on the bottom and that the green color thread was in the middle. 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

Louise Pratt wrote A Contact Zone‚ a short story about how many different cultures interact through Transculturation and contact zones. A contact zone is defined as “is the gap in which transculturation takes place- where two different cultures meet and inform each other‚ in uneven ways” (mariexotoni). In my owns words‚ a contact zone can be where two different people from different backgrounds‚ teachings‚ and traditions come together and share their experiences. Contact zones can be seen in every

Technology Devices to Overcome the Limitations of Sight and Hearing Humans have sight and hearing limitation. Without any devices‚ our sight and hearing was limited. Most of the limitation of sight can be overcome with the help of certain optical instruments such as magnifying glass‚ microscope‚ binoculars and others. The range of frequency of hearing in human 20 Hz to 20 000 Hz. It was different according to the age of a person. Hearing limitations can be overcome by using devices such as

with an electron microscope‚ since they will not survive in a vacuum. The magnification in magnetic electron microscopes is determined by the strength of the current passing through the electric and electromagnetic lens coils. Changing the current through the objective lens coil focuses the image. In the optical microscope the image is determined by absorption of light by the specimen; in the electron microscope the image results from a scattering of electrons by atoms of the specimen. Since
